摘要：
The design of photocatalysts for overall water splitting in visible light remains a huge challenge. Carbon quantum dots (CQDs)/Ag/Ag3PW12O40 nanocomposites have high photocatalytic activities for overall water splitting in visible light without electron acceptors or hole scavengers. In the present system, H-2 evolution was performed on Ag particles. O-2 evolution appears to be a result of the oxidation of H2O on the valence band of Ag3PW12O40, which is enhanced by promoted electron-transfer events at hybrid interfaces of the polyoxometalates and CQDs. The synergistic effects of CQDs, Ag, and Ag3PW12O40 enable the design of a water-splitting catalyst with a remarkably improved efficiency (with an active region of <650nm; apparent quantum yield approximate to 4.9% at 480nm) and operational stability.
