报告摘要：Energy technologies are an important and expanding part of scientific research in the 21st century. There is a great and pressing need to improve energy efficiency, reduce CO2 emissions by carbon capture, store cleaner fuels such as H2 in a safe manner, improve battery technologies, and generate fuels in a renewable fashion. In this presentation I will outline how computational research at UCL is improving materials and composites for these applications. I will discuss has metal doping can strongly improve the gas-storage (both CO2 and H2) properties of carbon-based materials, how nanostructuring can modify the hydrogen storage properties of MgH2 and the photocatalytic properties of TiO2 and graphitic carbon nitride, and how the defect chemistry of LiBH4 can influence the Li-ion mobility, with significant implications for applications as a solid-state Li-ion electrolyte.
