Enhanced photocatalytic hydrogen evolution by prolonging the lifetime of carriers in ZnO/CdS heterostructures

Chem Commun (Camb). 2009 Jun 21:(23):3452-4. doi: 10.1039/b904668b. Epub 2009 May 6.

Abstract

Coupled ZnO/CdS heterostructures based on the Z-scheme mechanism are demonstrated to be highly active photocatalysts for H(2) evolution under simulated solar light irradiation due to the greatly prolonged lifetime of photoexcited carriers.
