Separation Mechanism for Photogenerated Charge Carriers in Heterogeneous Photocatalysts

Hidehisa Hagiwara
In heterogeneous photocatalysts, it is very important to move photoexcited charges in the semiconductor to the reaction site on the surface without recombination. In this review, we describe the process of the photocatalytic reaction from photoexcitation of semiconductor photocatalyst to surface redox reaction, and summarized various researches on the charge separation of photogenerated electrons and holes in semiconductors reported up to the present.
