Construction of 2D Layered Bi2WO6/Ti3C2/g-C3N4 Heterojunction and Its Photocatalytic Hydrogen Production Performance
The construction of heterojunctions is usually considered as the main technological means to produce hydrogen from solar-driven photocatalytic hydrogen production.Among them,Z-scheme heterojunction photocatalysts have received increasing attention in the field of overall water splitting.In this paper,2D/2D/2D Bi2WO6/Ti3C2/g-C3N4 ternary Z-scheme photocatalyst were successfully constructed.The photocatalytic hydrogen production experiments were performed under visible light irradiation.The results showed that the 2D(two-dimensional)layered heterojunctions could promote the effective separation of photogenerated carriers,which in turn improved the catalytic activity.
