About the Project

Controlling selectivity of catalysts through the interaction of cobalt with promoters: a computational modelling investigation 

This project is dedicated to using computational simulations to understand the formation and application of supported Co nanocatalysts for Fischer-Tropsch synthesis, under the supervision of Dr Andrew Logsdail (Cardiff), Prof. Sarah Haigh (Manchester) and Dr James Paterson (bp). 

Achieving net zero emissions will require multiple technologies to be developed and realised in the coming years. Fischer-Tropsch (FT) is one such technology, with emergent application in the conversion of waste into ultra clean fuels, leading to approximately 80% emission reductions over landfill. Over several years, an understanding of the Co-based FT catalyst has been developed, and the role of promotional additives has proven critical during synthesis, catalyst treatment, and FT synthesis [1]; however, knowledge of how these promoters affect the chemistry remain poorly understood, with most progression to-date based on observation and hypothesis. Using state-of-the-art molecular modelling, this project aims to elucidate exactly how these additives impact catalyst formation and the subsequent application in FT synthesis, providing foundations to make more robust, sustainable and efficient catalysts. 

The project will use a multiscale combination of first-principles density functional theory (DFT) and microkinetic simulations to investigate the chemistry of interest (interaction of Co and promoters with catalyst support; phases stability of CoOx/MOx during pre-catalyst reduction; selectivity of reaction products with changing Co catalyst structure). Experience with performing modelling simulations and programming are desirable but not essential, as full training will be provided for suitable candidates. Candidates should have a demonstratable interest in theoretical or computational chemistry, heterogeneous catalysis, molecular or solid-state physics, materials science, or closely related topics. 

This project is supported by bp and hopes to support them to generate cleaner fuels to lower global emissions. You will receive regular mentoring from bp and be able to spend time in an industrial research environment if this is of interest. Nonetheless, the project aims are fundamental, so we expect to publish high impact outputs in world leading journals after industrial review. There will be opportunities to perform simulations on leading national and international facilities, and to present your work at international conferences.
