Z-scheme Ag3PO4/POMs/GO heterojunction with enhanced photocatalytic performance for degradation and water splitting

Abstract

To develop solar-light-driven photocatalysts with high activities and structure stability, Ag3PO4/POMs/GO heterojunction has been successfully prepared by a facile method at room temperature, which shows remarkable enhanced activity and stability in photocatalytic degradation and H2 production form water-splitting under simulated solar light. The degrading rate of Ag3PO4/POMs/GO is 1.8 times and 1.2 times that of Ag3PO4 and Ag3PO4/POMs, respectively. The H2 production of Ag3PO4/POMs/GO is 2.0 times that of Ag3PO4/GO. The enhanced photocatalytic performance of Ag3PO4/POMs/GO is attributed from the increased surface area, electronegativity and protection from photocorrosion. The Z-scheme system of Ag3PO4/POMs/GO effectively promotes charges separation, resulting in enhanced photocatalytic performance under simulated solar light.
