Abstract

The titania-nanotube-supported Pt (Pt/Tnt) catalyst was prepared by the photochemical deposition of Pt complex on the titania-nanotube (Tnt) synthesized by the alkaline hydrothermal method. The physicochemical properties of Pt/Tnt catalyst were investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, N₂ adsorption and desorption isotherms, temperature-programmed reduction and X-ray photoelectron spectroscopy. The Pt/Tnt catalyst exhibited mixed-valence Pt nanoparticles (1-3 nm) dispersed uniformly on the surface of Tnt with a Brunauer-Emmett-Teller surface area of 187 m²/g. The results of the temperature-programmed desorption of CO₂ indicated the CO₂ adsorption capacity of Tnt was highly enhanced by the supported Pt nanoparticles. In situ Fourier-transform infrared spectroscopy demonstrated that the Pt/Tnt catalyst was highly active for the CO₂ hydrogenation toward methane production at relatively low temperature of 100 °C.
