One-step synthesis of flower-like WO3/Bi2WO6 heterojunction with enhanced visible light photocatalytic activity
Source abstract
Abstract
WO3/Bi2WO6 heterojunctions with flower-like structure were prepared by a facile hydrothermal process without any surfactants or templates. In the heterojunctions, WO3 nanoparticles were incorporated into three-dimensional flower-like hierarchical Bi2WO6. The WO3/Bi2WO6 samples showed much higher photocatalytic activity than pure Bi2WO6 did for rhodamine B degradation under visible light irradiation. This could be ascribed to the formation of n–n type heterojunction, which resulted in the high transfer rate of the photo-generated electron–holes between WO3 and Bi2WO6 and confirmed by photoluminescence and photocurrent measurements.
