Abstract:
Current human society has relied heavily on the consumption of non-renewable fossil fuels (>80% in the global energy supply sectors), however, the utilization of fossil fuels is facing tremendous stresses: environmental concerns from the unfavorable emissions from the combustion of fossil fuels and the depletion of fossil fuels. For 21st century Energy Chemistry, one of the major missions is exploring clean and sustainable energy, whose mid- and long-term goals center on: developing energy-efficient techniques to extend the life-time of fossil fuels, and exploiting more sustainable energy sources, such as solar, biomass, wind energy, and so on, as alternatives for fossil fuels. These goals are highly dependent on the progress of materials chemistry.

These tasks need multi-disciplinary synergistic efforts beyond traditional chemistry itself. The Oxford chemistry energy group (PPE) has tens of years of experience in materials chemistry. In this presentation, I will briefly overview my recent progress on catalytic materials for energy-efficient combustion, CO2 utilization and solar energy harvesting. The results and challenges for the lab- and pilot-scale catalytic conversion of methane (combustion and reforming) will be highlighted. Promising advances in novel semiconductor photocatalysts and their application for solar fuels and environmental clean-up will be briefly introduced as well.
