[School of Engineering PhD Scholarships] Operando-Guided Design of Dual-Atom Catalysts for CO₂-Assisted Ethane Dehydrogenation

About the project

About the Project Ethylene sits at the heart of the chemical industry: it is the starting point for plastics, pharmaceuticals, detergents, and countless everyday products. Yet the way we produce it today, mainly through steam cracking, is one of the most energy-intensive processes in the sector. To meet global net-zero targets, the chemical industry must adopt cleaner and more energy-efficient production routes. A promising alternative is CO₂-assisted ethane dehydrogenation, a process that uses CO₂ not as a waste product, but as a reactant. This approach can lower the temperature needed to make ethylene while converting CO₂ into useful molecules, offering a pathway towards more sustainable manufacturing. This PhD project will give you hands-on training in designing, synthesising and testing a new class of catalysts to make this process cleaner, more efficient and more durable. These “dual-atom catalysts” contain two closely positioned metal sites that work together to activate reactants and steer the reaction towards ethylene. By placing these catalysts inside small-pore zeolites, we aim to improve their stability while enhancing local CO₂ adsorption. Using state-of-the-art operando X-ray absorption and infrared spectroscopies, you will watch these catalysts at work under real reaction conditions, tracking changes in their local atomic environment as they happen. These insights will guide the rational development of next-generation materials for sustainable ethylene production. The PhD position will be based at the world-leading Harwell Science and Innovation Campus in Oxfordshire, the UK's leading science innovation and technology campus, situated 20 minutes from Oxford and one hour from London. This will facilitate research activities with Diamond Light Source, the UK's national synchrotron facility. Diamond produces intense beams of X-rays to probe materials at the atomic scale, making it an exceptional place to study catalysts under working conditions. You will also benefit from the world-class research environment of the UK Catalysis Hub, which brings together experts, facilities and training in modern catalytic science. Together, these opportunities will enable comprehensive training in catalyst synthesis, performance evaluation and advanced spectroscopic characterisation. This project is expected to start in September 2027. Before you apply: We strongly recommend that you contact the supervisors for this project before you apply.
