英文摘要: The Eu-doped TiO2 nanoparticles were successfully prepared by a simple sol-gel method. The properties of the catalysts were characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), energy dispersive spectrometer (EDS), N2 adsorption-desorption, UV-vis diffuse reflectance and photoluminescence (PL) spectroscopy. The results indicated that Eu-TiO2 catalysts had a high specific surface area, enhanced visible light response and low recombination rate of electron-hole pairs. The photocatalytic performances of Eu-TiO2 catalysts for CO2 reduction were investigated under 9h irradiation of a 300W Xe arc lamp. The maximum yields of CH4 and CO over the optimized Eu-TiO2 catalyst were 65.53μmol/g.cat and 42.91μmol /g.cat, respectively, which were approximately 13 times and 1 times higher than that of pure TiO2. The enhanced photocatalytic performance could be ascribed to the high-efficiency separation of photo-generated electron-hole pairs. © 2018 Elsevier Ltd. All rights reserved. Citation statistics:
