讲座题目：Development of Efficient Catalytic Materials for Solar Energy Capture
Global energy concerns motivate the development of new and improved technologies for solar energy capture, with semiconductor photocatalysis and photothermal catalysis expected to play key roles in meeting the energy needs of future societies. This talk will overview some of our recent research aimed at solar-driven catalyst development for H2 production in alcohol-water systems, the reduction of CO2 to CO and the conversion of N2 to NH3. Our research has identified 2D nanosheet photocatalysts made from earth-abundant elements, especially layered double hydroxides (M2+M3+-LDH, where M2+ = Ca2+, Mg2+, Mn2+, Fe2+, Co2+, Ni2+ or Zn2+ and M3+ = Al3+, Ga3+ or Fe3+) and graphitic carbon nitride (g-C3N4), as promising low cost candidates for the aforementioned processes under direct sunlight. Strong emphasis here will be placed on the importance high resolution transmission electron microscopy (HRTEM), synchrotron-based X-ray spectroscopies (XPS, EXAFS) and DFT calculations for the understanding of catalyst function and ultimately performance optimization via exploitation of structure-activity relationships.
