Facilitating charge transfer by giant magnetoresistance effect for high-efficiency photocatalytic hydrogen production

Abstract

In this work, a CoCu alloy magnetic unit was implanted in photocatalytic system to improve photoinduced charge separation efficiency by regulating electron transfer pathway via giant magnetoresistance (GMR) effect, which achieved significantly enhanced hydrogen production activity driven by visible light. The amount of H2 produced in 3 h over the Pt@CoCu alloy decorated graphene (G) photocatalyst was about 12.2 times higher than that of Pt/G, and the highest apparent quantum efficiency (AQE) reached 34.4% at 520 nm.
