The development of solar powered photo-activated materials promises to have a major impact in a variety of future applications in environmentally friendly science, such as solar energy conversion (solar fuel and photoelectrocatalysis) and artificial photosyntheiss. For this research a multi-template strategy for synthesizing hollow nanocubes of CuO-TiO2-xNx, a new hybrid material that photocatalytically converts CO2 into methane under solar irradiation, has been developed. In addition this talk will review researches related to the direct conversion of solar energy to chemical fuels (i.e.,hydrogen) utilizing a combination of a visible or infrared light absorber such as Si with non-Pt hydrogen evolution reaction (HER) catalysts such as cubanes made of MoxSy. Prof. Chorkendorff and et al. showed that the bioinspired molecular co-catalysts such as incomplete cubane-like clusters (Mo3S4) efficiently catalyze the evolution of hydrogen when coupled to a p-type Si semiconductor that harvests red photons in the solar spectrum. |
