Abstract

In this work, TiO2-WO3 composite materials were forged by sol-gel method and the forged samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and UV-vis diffuse reflectance spectroscopy. The tough interaction in the interface of TiO2-WO3 heterostructures and the solar spectral response of TiO2 and WO3 reduce the electron-hole pair recombination rate and enhance the photoelectrochemical activity. The TiO2-WO3 heterostructures also show good adsorption ability for organic pollutants. This study testified that the fabricated TiO2-WO3 heterostructures are expectation materials for efficient water splitting as well as adsorption and photocatalytic wipe off organic pollutants.
