Abstract

Abstract:

The fabrication of multicomponent heterojunctions is an effective strategy to improve the performance of TiO₂ based photocatalysts. We provide a new strategy for improving the charge separation and photocatalytic performance of ZnO/TiO₂ composites by the formation of multichannel charge separated heterojunctions. ZnO/P25 composites were prepared by an incipient wetness impregnation method, and applied for the photocatalytic destruction of gaseous toluene. The ZnO/P25 composites consist of anatase TiO₂ (ATiO₂), rutile TiO₂(RTiO₂) and hexagonal zincite structures. The parasitic phase of ZnO in P25 leads to the formation of ZnO(002)/ATiO₂(101)/RTiO₂(110) heterojunctions that exhibit enhanced light absorption and improved multichannel electron/hole separation. ZnO/P25 heterojunctions can completely oxidize toluene into CO₂ and H₂O under ultraviolet light irradiation at room temperature, and show enhanced photocatalytic activity in comparison with P25 owing to the efficient electron-hole separation. Such a multichannel charge separated design strategy may provide new insight into the design of highly effective photocatalysts and their potential technological applications.
