One-step synthesis of Bi2WO6/TiO2 heterojunctions with enhanced photocatalytic and superhydrophobic property via hydrothermal method
Source abstract
Abstract
A simple hydrothermal method was developed to synthesize Bi2WO6/TiO2-layered heterojunctions. The effect of amount of TiO2 and sodium dodecyl benzene sulfonate, reaction temperature, and reaction time on the structure and morphology of Bi2WO6/TiO2 heterojunctions was investigated. The results suggest that the structure and morphology of Bi2WO6/TiO2 heterojunctions can be tuned by changing reaction conditions. Then the heterojunctions were used to catalyze the degradation of methyl orange, quinoline blue, Rhodamine B, and methylene blue under visible light (Xe-lamp, 300 W). And their superhydrophobic property was characterized. It shows that TiO2/Bi2WO6 heterojunctions not only exhibit excellent photocatalytic activity, but also show significant superhydrophobic property. Moreover, a possible photocatalytic mechanism was also proposed.
