文摘

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, N₂-physisorption, UV–vis diffuse reflectance spectroscopy and photoluminescence spectroscopy. Loading NiS nano-clusters can significantly enhance the photocatalytic H₂ evolution performance of TNTs. The optimum NiS loading content was found to be 8 wt% and the corresponding hydrogen production rate is ca. 7486 µmol/h/g, being about 79 times higher than that of pure TNTs. This enhancement of photocatalytic H₂ evolution was attributed to the synergistic effect between NiS and TNTs.
