Paper Title:
The Characterization and Photocatalytic Properties of Mesoporous WO3•0.33H2O•NiO Nanocrystalline Synthesized through Using the Microwave Radiation Method
  Abstract

Mesoporous WO3•0.33H2O was synthesized by the microwave radiation method using surfactant as the template-directing agent, and the template was removed by Soxhlet extraction. The degree of framework substitution had been monitored by means of powder X-ray diffraction (XRD), nitrogen adsorption, and UV-vis diffuse reflectance (DRUV) spectroscopy techniques. Nitrogen adsorption data and XRD patterns confirmed that, the structure, high surface area, and uniform pore size distribution were maintained in the crystallized samples. The photocatalytic activity for the photo-oxidation of gaseous formaldehyde on the mesoporous WO3•0.33H2O synthesized was improved by NiO loading, the photocatalytic activity was higher than both that of the materials synthesized using calcination in high temperature and commercial Degussa P25 TiO2 under visible light and UV irradiation.
