 报告摘要:

Conversion of the most abundant renewable energy source on our planet, solar energy to fuel (artificial leaves concept) has been attracting more and more attention over the last ten years after a long-term silence, which involves three key processes: charge carriers generation, separation and transportation, final utilisation on the surface of a photocatalyst.

This lecture will start with a summary of the potentials of the different renewable energy sources, e.g. solar, biomass, wind, geothermal and hydroelectric energy, and then move to the benchmark work of solar energy conversion. In particular our recent results including,  i) mechanism of solar H2 synthesis from water, ii) CO2 photoconversion and iii) photocatalytic water/air purification will be presented.1-5 Further new material strategy based on our mechanistic understanding will be discussed, which was tested for both water splitting for H2 evolution and CO2 photoreduction. For example, a new inorganic heterojunction cascade achieves a ~1.6% quantum yield at 400nm for CO2 photoreduction to valuable chemicals.
