Fundamental understanding of photocatalysis and photoelectrocatalysis for solar fuel production
This lecture presents the research progress on solar fuel productions from photocatalysis and photoelectrocatalysis (PEC) processes with the emphasis on the fundamental understanding. Solar fuel production currently is mainly refereeing the hydrogen production via overall water splitting (2H2O®2H2 + O2) and chemical fuels production through artificial photosynthesis, namely the reaction H2O + CO2. These reactions have been regarded as the most important and promising strategy to convert the solar energy into chemical energy, and to meet the demand of human society for sustainability. Extensive efforts have been made in developing the efficient photocatalytic and photoelectrochemical systems for these reactions, including mainly semiconductor based photocatalysts, molecular photocatalysts and hybrid of nature and artificial photosynthesis systems.
