A team publishing in Nanoscale Advances this year built porous nickel and cobalt phosphosulphide heterostructures on molybdenum carbide supports, and got overpotentials down to 153 and 157 millivolts for hydrogen and oxygen evolution. That's a real number you can compare your own catalyst against. If you've got access to an electrochemical workstation, there's a whole dissertation in testing whether a different metal pairing or support material can beat those figures under the same test conditions.

Chemical Reviews ran a piece in August 2025 on anion-exchange-membrane water electrolysis, and the authors were blunt about it: achieving high cell efficiency with an alkali-free water feed, including seawater, is what everyone wants but nobody's nailed yet. Most systems still need a dilute alkaline electrolyte to work properly. That gap alone could carry a strong masters or PhD project, especially if you pair electrochemical testing with some membrane characterisation work.

Then there's the aqueous glycosylation question, covered in Chemical Reviews in October 2025. Organic chemists have spent decades treating glycosylation as something you only do under strictly anhydrous conditions. Fischer and Pedersen's review makes the case that water-based glycosylation is underdeveloped as a green chemistry frontier, not because it doesn't work, but because almost nobody's tried to make it work well. A synthesis-focused dissertation testing glycosylation yields in aqueous versus anhydrous conditions would sit right in that gap.

On the policy side, ECHA published an updated proposal in August 2025 to restrict PFAS substances under REACH. The debate in EuChemS and the wider chemistry press right now is less about whether PFAS are harmful (that's settled) and more about whether viable substitutes actually exist at scale. That's a genuinely open question, and it works equally well as a synthesis project, an analytical detection-method project, or a literature-based feasibility review, depending on what your department can support.

And copper catalysis has its own unresolved problem. A 2026 Chemical Society Reviews paper on atomically precise copper nanoclusters points out that copper oxidises easily and loses structural stability under photocatalytic conditions, which limits how far you can push it. If your interest is in stabilisation chemistry rather than catalysis performance itself, that's a narrower, more supervisor-friendly angle than "improve copper catalysts" would be.

A lab-based comparison of cell efficiency using deionised, tap, and simulated seawater feeds against a standard dilute-alkaline control.

Gap: Chemical Reviews (August 2025) states that high-performing alkali-free anion-exchange-membrane electrolysis "remains highly desirable" but currently underdelivers compared to alkaline-fed systems.

Methodology: quantitative, controlled electrolysis trials across at least three feed conditions, measured against cell voltage and Faradaic efficiency.

Data source: in-house electrochemical workstation data, cross-checked against published benchmark values in the source review.

Source: Fischer, Pedersen, Chemical Reviews, October 2025, DOI 10.1021/acs.chemrev.5c00638.

A feasibility-focused literature and lab review of one specific PFAS replacement candidate, not the whole PFAS class at once.

Gap: ECHA's August 2025 REACH restriction proposal has forced the substitute question from theoretical to urgent, but named substitutes vary hugely in maturity by application.

Methodology: mixed methods, secondary literature review plus (where lab access allows) contact-angle or surface-property testing of a candidate substitute.

Gap: MOFs remove antibiotics including amoxicillin, doxycycline, levofloxacin and ciprofloxacin through adsorption, and plant-based MOFs are emerging as eco-friendly alternatives, but scalability and stability challenges remain unresolved.

Methodology: batch adsorption experiments comparing a plant-based MOF against a conventional MOF for one named antibiotic, measured across multiple pH and concentration conditions.

Data source: your own adsorption isotherm data, plus DOI 10.1515/revic-2024-0119 for baseline comparison figures.

Source: Reviews in Inorganic Chemistry, 2025.

Source: Chemical Society Reviews, Volume 54, 2025.

Gap specific to 2025-2026: ECHA's August 2025 REACH restriction proposal has increased demand for reliable low-concentration PFAS detection, and current mass spectrometry methods vary widely in sensitivity across PFAS subclasses.

Methodology: comparative analytical method validation, LC-MS/MS testing across spiked groundwater samples at defined concentration ranges, n ≥ 5 replicates per concentration.

Gap specific to 2025-2026: the substitution debate following the August 2025 REACH proposal is happening at the level of whole product categories, but feasibility varies enormously between, say, textile coatings and food packaging, and few studies isolate one category cleanly.

Methodology: structured literature review combined with a feasibility scoring framework (performance, cost, regulatory readiness) applied to 3 to 5 named substitute chemistries within one product category.

Contribution: gives a clear, bounded scope that avoids the "fishing expedition" rejection the brief specifically flags, since the category and scoring criteria are fixed in advance.

Data access: ECHA public dossiers, EuChemS magazine, supplier technical data sheets for named substitutes.

"Which topic is best for research in chemistry?" — Google People Also Ask

There's no single best topic, only the best fit for your access and interests. Green chemistry and sustainability-linked topics currently have the easiest path to supervisor approval, given current UKRI and EPSRC funding priorities. If you want a topic matched to your exact situation, our free custom topic service can do that in 24 hours.

"What are 5 good research topics?" — Google People Also Ask

PFAS substitutes, single-atom catalysis, MOF-based water treatment, AI-assisted solvent substitution, and copper nanocluster stabilisation are all genuinely open right now. Each one traces back to a named 2025 or 2026 publication, not a recycled list. We can narrow these to your degree level and lab access for free.

"Which topic is best for dissertation?" — Google People Also Ask

The best topic is one your supervisor approves on the first pass, with a clear question, named variables, and a realistic scope. Common rejection reasons include vague research questions and overambitious scope, both avoidable with the right framing. Our researchers check every topic against exactly these criteria before you see it.

"How to write a chemistry dissertation?" — Google People Also Ask

Follow the standard structure: introduction and literature review, methodology, results, discussion, conclusion. Expect the literature review alone to take three to six months before experimental work starts. If you'd like help scoping your methodology section specifically, get in touch and we'll talk it through.

"I'm going into yr 13 and I'm having trouble coming up with a question to answer for a chemistry dissertation as I'm not sure how to discuss any answers I find, it's just right or wrong." — The Student Room

Reframe binary questions into comparison or "how much" questions so there's something to discuss. A question with only one correct answer leaves no room for analysis once you've found it. If you're stuck reframing your own idea, send it to us and we'll help you turn it into something discussable.

"Do you have any suggestion of some topic thesis related to chemistry? If you have some ideas kindly list down here." — ResearchGate

Work backwards from your equipment access, subfield interest, and degree level before picking a topic. That filtering gets you to a genuinely workable option faster than browsing a long list. Our free service does this filtering for you in 24 hours.

"What are good topics for a PhD dissertation in Chemistry?" — Quora

PhD topics need systematic variation built in from the start, not a single test of a single condition. Aim for something connected to a funded priority like catalysis for net zero or circular economy chemistry. We can help you scope a PhD-level project that a funding panel would actually recognise.

"How would quantum mechanics allow us to develop new types of technology?" — The Student Room

Quantum mechanics underpins computational chemistry dissertations, particularly reaction modelling and materials prediction work. This route needs computing time rather than lab bench access, which sidesteps equipment oversubscription entirely. If a computational topic interests you, we can match you to one that fits your department's resources.

Undergraduate: Keep your question bounded to one clear variable and one clear outcome. "Investigating catalysis for sustainable energy" is too broad for this level, whereas "evaluating the efficiency of a specific MOF-derived catalyst for oxygen evolution reaction under controlled laboratory conditions" gives you something you can actually finish in the time you've got. Literature-review-based dissertations are more acceptable at this level than at masters or PhD, so if lab access is limited, a structured secondary research project (like the PFAS substitute feasibility topic above) is a legitimate, well-scoped choice.

Masters: You're expected to name specific materials, compounds, or conditions rather than working in general categories. "Analysing environmental pollutants and their impact" won't get approved; "quantifying the adsorption capacity of three specific MOF composites for removing ciprofloxacin from simulated wastewater" will. Right now, supervisors are saying yes more often to projects that pair a real experiment with some DFT or molecular dynamics modelling, rather than picking one or the other. Green chemistry angles have an easier time getting approved too, mostly because they line up with where the funding's going. Expect to spend real time on instrument booking, since NMR, mass spectrometry and electron microscopy access is often oversubscribed across UK chemistry departments.

PhD: Your project needs systematic variation built into the design from the outset, not a single test of a single condition. "Developing new materials for energy applications" is too broad; "designing, synthesising and characterising a novel series of single-atom catalysts with systematic variation of metal centres and supports for electrochemical CO₂ reduction" is the right scope. Supervisors are currently most impressed by interdisciplinary framing (chemistry combined with AI, environmental science, or materials science), clear methodology with contingency plans, and topics that engage directly with 2025-2026 developments rather than settled ground. If your project involves human-derived material (even wastewater samples, in some cases) or fieldwork, factor in ethics approval time well before your planned start date.

NIST Chemistry WebBook: free and searchable, this holds chemical, spectral and thermophysical data on thousands of compounds. Use it when you need reference spectra or thermodynamic values to compare against your own experimental results, no registration required.

ChemSpider (RSC): a free chemical structure database giving fast access to over 100 million structures pulled from hundreds of data sources. Good for confirming compound identity, structure verification, and cross-referencing synonyms across your literature review.

PubChem (NIH): the largest freely accessible chemical information database there is. Use it for bioactivity data, safety data, and compound properties, particularly useful if your dissertation touches medicinal or environmental chemistry.

ChemRxiv: a free, open-access preprint archive for chemistry. Check here for the most recent unpublished findings in your subfield, since preprints often appear months before the peer-reviewed version, which matters if you want your literature review genuinely current.

PQDT Open: gives you free full-text access to open-access dissertations and theses. Read a few completed chemistry dissertations here before you start writing your own, so you know what scope and structure examiners actually expect.

A dissertation built around a genuine 2025-2026 literature gap, like the aqueous glycosylation question raised in Chemical Reviews or the copper nanocluster stabilisation problem from Chemical Society Reviews, carries real publication potential if your findings hold up. Premier Dissertations' publishing support has helped students place strong dissertation work in respected, peer-reviewed venues, though that's a genuine next step for work that earns it, not a guarantee attached to every project. If publication interests you, our dissertation publishing services and Scopus publication support are worth a look once your research is further along.

Most chemistry topic lists online read the same because they're built the same way — scraped from old pages or generated once and never touched again. Ours aren't. Every topic on this page traces back to a named 2025 or 2026 source, and every one has been checked by someone who actually understands chemistry research, not just chemistry keywords.

That matters more than it sounds. A supervisor can tell within a paragraph whether a topic has a real research question behind it or whether it's just a subject area dressed up as one. We'd rather you walk into your first supervision meeting with something that survives scrutiny.

Copper nanocluster stabilisation, aqueous glycosylation, and alkali-free electrolysis are genuinely open questions in chemistry research right now, each one pulled from a paper published in 2025 or 2026. No AI tool trained before this year could hand you these gaps, because the papers that named them didn't exist yet. We've been matching students to topics like this, and we're just as ready to help with what comes after the topic — the proposal, the methodology, the whole dissertation.
