Core-Shell WO3/TiO2 Nanorod Heterostructures for Solar Light Photocatalysis

Article Preview

Abstract:

Heterojunction photocatalyst containing one dimensional nanostructures exhibits interesting size, shape and material-dependent photocatalytic properties compared to single-component counterpart. In this work, we develop a simple two-step strategy to WO3/TiO2 heterojunction based on WO3 nanorods and TiO2 nanoparticles. The as-obtained heterojunction features core-shell morphology and has the advantage of extended solar light response, enhanced chemical stability and easy recyclability. As such, it exhibits high photocatalytic activity toward organic pollutants degradation including rodamine B dye and gaseous acetaldehyde.
