One-dimensional Bi2WO6/RGO Nanobelts Photocatalyst for Efficient Hydrogen Generation

Abstract

Reduced graphene oxide (abbreviated as RGO) possesses a fantastic ability to accept and transfer electrons. Bi2WO6 semiconductor is a superb visible light catalytic material, which not only owns narrow band gap, stable property, but also is non-toxic. Hence, Bi2WO6/RGO nanobelts are rationally devised and manufactured by combining electrospinning and calcination technique in this work. The hydrogen generation efficiency of Bi2WO6/2%RGO nanobelts reaches up to 492.22 µmol h^-1, which is 2.52 times that of pure Bi2WO6 nanobelts. The result can be ascribed to the addition of RGO, which can heighten the capture intensity of Bi2WO6/2%RGO nanobelts in the visible and ultraviolet light regions, and the conductivity of RGO can quickly transfer electrons, thus promoting the separation and transfer of charge carriers. Therefore, Bi2WO6 nanobelts photocatalyst has a broad application prospect in the field of photocatalytic hydrogen generation.
