This proposal titled "Converting methane into green fuels using electrochemical devices (COMFUELS)"will achieve efficient electrochemical methane conversion in a gas diffusion methane conversion cell through few-layer 2D materials-supported, transition metal oxide catalysts. We will exploit our expertise in the preparation of metal nanostructures by electrodeposition, preparation and modification of few-layer 2D materials, and electrocatalysis. This will provide a new generation of high-performing catalysts for sustainable methane conversion into value-added fuels, enabling the scientific community to exploit the potential of gas diffusion methane electrolyzers. The fellow, Manila Ozhukil Valappil, is an expert on 2D nanostructures and electrocatalysis. The supervisor, Prof. Maria Escudero Escribano at the Catalan Institute of Nanoscience and Nanotechnology, ICN2 in Barcelona, has long-standing expertise in (spectro)electrochemistry, electrocatalysis, materials science and surface nanostructuring for various electrochemical applications, and has secured an ERC-Consolidator Grant (June,2023-present) on tailored materials for electrochemical methane activation and conversion into valuable chemicals such as methanol. Well-established advanced materials and electrochemical characterization facilities at ICN2 ensure the project’s success and will provide a unique environment for the development of MOV.
