Abstract

The H3PW12O40-titania composite materials were prepared by nonionic-surfactant templating strategy combined with hydrothermal treatment. X-ray diffraction, N2 adsorption, elemental analysis, UV-visible spectroscopy, photoluminescence and X-ray photoelectron spectroscopy were used to characterize the prepared composite materials. The results indicated that the addition of H3PW12O40 did not influence the crystallization of TiO2. Hybridization of Ti 3d orbit and W 5d orbit caused the decreased bandgap energies of H3PW12O40-titania composite materials, leading to the increased visible light absorption. The obtained catalyst exhibited outstanding photocatalytic activity and stability under visible light.
