Solar-driven water splitting or reduction of CO2 on photocatalysts represents one promising technique to convert solar energy into chemical energy. One current central task is to develop efficient solar-driven photocatalysts. The efficiency of photocatalysis is co-determined by three basic processes including light absorption, charge separation and catalytic conversion. Concerning these three basic processes, we focus on three strategies, 1) band engineering, 2) heterostructuring and 3) facet controlling, to tailor the properties of photocatalysts. The context of this talk mainly includes three parts, 1) the crucial role of spatial distribution of dopants or defects in realizing the redshift of the whole light absorption edge for a wide visible light absorption, 2) three kinds of core-shell engineered heterostructures with the ability of realizing spatial separation of photogenerated charge carriers, and 3) tailoring the exposure of different facets of photocatalysts.
