Reduced graphene oxide (abbreviated as RGO) possesses a fantastic ability to accept and transfer electrons. Bi 2 WO 6 semiconductor is a superb visible light catalytic material, which not only owns narrow band gap, stable property, but also is non-toxic. Hence, Bi 2 WO 6 /RGO nanobelts are rationally devised and manufactured by combining electrospinning and calcination technique in this work. The hydrogen generation efficiency of Bi 2 WO 6 /2%RGO nanobelts reaches up to 492.22 µmol h -1 , which is 2.52 times that of pure Bi 2 WO 6 nanobelts. The result can be ascribed to the addition of RGO, which can heighten the capture intensity of Bi 2 WO 6 /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, Bi 2 WO 6 nanobelts photocatalyst has a broad application prospect in the field of photocatalytic hydrogen generation.
