Abstract

Herein, we demonstrate the synthesis of Bi₂MoO₆ nanosheet array followed with in-situ electrodepositing ZnO layer, resulting in Bi₂MoO₆/ZnO heterojunction nanosheet array. The thickness of nanoparticle-based ZnO layer on the surface of Bi₂MoO₆ nanosheets can be rational controlled by regulating the electrodepositing time. The combination of oriented Bi₂MoO₆ nanosheet array and ZnO layer could not only enhance the conductivity and surface area but also facilitate the charge separation. As expected, the heterojunction electrode yields a photocurrent density of 430 µA/cm² at 0.8 V_SCE, which is much higher than that of pristine Bi₂MoO₆ and ZnO nanosheet array.
