Metal-support interactions: single atoms Vs nanoclusters. This project aims to fundamentally understand the catalytic mechanism at an atomic level through metal-metal and metal-metal/support interactions. The optimised configuration of active sites for a specific reaction is consequently identified, providing the design principles of novel catalysts. The precisely control of synthesis for such active sites and assembly of the target active sites into a catalyst will deliver a completely new meth ....Metal-support interactions: single atoms Vs nanoclusters.

Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all ox ....Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all oxide-based PEMFC technology using a recently developed sintered and heteropolyacid functionalised mesoporous silica membrane. The utilisation of all-oxide-PEMFCs using non-precious metal catalysts is expected to significantly enhance the power density, reduce costs, and enhance the commercial viability of PEMFC technologies.Read moreRead less

This project aims to investigate corrosion behaviour of heat resistant alloys in the presence of both hydrogen and water vapour, mechanisms of water transport in oxide scale, and the effect of hydrogen on water vapour corrosion. Alloying effects on corrosion rates will be defined and methods of slowing or preventing water vapour corrosion in the presence of hydrogen will be devised. The results will provide a basis for improved design/selection of heat resisting alloys for hydrogen production and hydrogen utilisation industries.Read moreRead less
