Description
Global energy concerns motivate the development of new and improved technologies for solar energy capture, with semiconductor photocatalysis expected to make an important contribution towards satisfying the energy needs of future societies. This talk will overview some of our recent research aimed at photocatalyst development for H2 production in alcohol-water mixtures, focussing primarily on transition metal oxide (TiO2), oxynitride (LaTiO2N, TaON) and nitride (Ta3N5) systems. The potential of 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), for future solar energy harvesting and fuel production will also be explored. Strong emphasis here will be placed on the importance high resolution transmission electron microscopy (HRTEM), synchrotron-based X-ray spectroscopies (XPS, NEXAFS, EXAFS) and supporting DFT calculations to the understanding of photocatalyst function and ultimately performance optimization via exploitation of structure-activity relationships.
