Preparation of CuO-Decorated Core-Shell Montmorillonite-TiO₂ Colloids and their Photocatalytic Activity for Hydrogen Evolution from Water

Abstract:

CuO-decorated core-shell montmorillonite-TiO₂ colloids were prepared and characterized with transmission electron microscope, powder X-ray diffraction analysis, Brunauer-Emmett-Teller analysis and UV-vis spectrua. Meanwhile, their photocatalytic activity for hydrogen evolution from water was explored under UV irradiation using methanol as a sacrificial reagent. The results indicate that they are an efficient photocatalyst with a rate of H₂ evolution of 219 μmol·h^-1·g^-1 which is higher than that of anatase TiO₂ nanoparticles.
