Heterojunction with nanosized interfacial contact stands out in promoting the transfer photoinduced interfacial carriers. Herein, a heterojunction with nanosized interfacial contact was designed by constructing BiVO4/Bi4V2O11 element-copied heterojunction nanofibres. The heterojunction was formed by combining BiVO4 nanofibres and embedded Bi4V2O11 nanocrystals. They offered favourable interfacial contact on nanosized level. The photocatalytic performance of heterojunction nanofibres with nanosized interfacial contact were indicated to be markedly enhanced compared with that of pure BiVO4 nanofibres. Furthermore, we also observed a 10-fold enhancement in the photocurrent intensity for the heterojunction nanofibres with nanosized interfacial contact, indicating the enhancement of photocatalytic properties was attributed to the nanosized interfacial contact with wonderful interfacial photoinduced carriers transfer behavior.
