Preparation and photocatalytic properties of Bi₂MO₆ (M =W, Mo) semiconductor composite TiO₂ nanowires

Abstract

Photocatalytic degradation of pollutants using nano-TiO2 is one of the most promising strategies to solve environmental pollution problems. In this paper, we systematically studied Bi2WO6 composited TiO2 nanowires to obtain the optimum composite proportion. Moreover, the TiO2 nanowires were composited with Bi2MoO6 and Bi2WO6/ Bi2MoO6 in the optimum proportion, respectively. The results showed that the Bi2WO6/ Bi2MoO6 composited TiO2 nanowires had the best catalytic performance, and the degradation rate of methyl orange reached 78.4%, which was 3.41 times higher than that of pure TiO2 nanowires. The current work is expected to provide new ideas for the research and development of high-efficiency photocatalytic materials.
