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

Author affiliations

Abstract

In this work, a CoCu alloy magnetic unit was implanted in a photocatalytic system to improve photoinduced charge separation efficiency by regulating the electron transfer pathway via a 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.
