摘要：
TiO2 nanotubes (TNTs) with nickel sulfide (NiS) co-catalyst were prepared by a simple solvothermal method and characterized by X-ray diffraction, transmission electron microscope, N-2-physisorption, UV-vis diffuse reflectance spectroscopy and photoluminescence spectroscopy. Loading NiS nano-clusters can significantly enhance the photocatalytic H-2 evolution performance of TNTs. The optimum NiS loading content was found to be 8 wt% and the corresponding hydrogen production rate is ca. 7486 mu mol/h/g, being about 79 times higher than that of pure TNTs. This enhancement of photocatalytic H-2 evolution was attributed to the synergistic effect between NiS and TNTs. (C) 2015 Science Press and Dalian Institute of Chemical Physics. All rights reserved.
