Abstract

Abstract:

A highly active assembled Pt/TiO₂ catalyst (Pt/TiO₂-AS) was synthesized using a simple directadsorption method, in which uniformly dispersed Pt nanoparticles were directly loaded on a TiO₂ support. Compared with Pt/TiO₂ produced by wet impregnation (Pt/TiO₂-WI), the Pt/TiO₂-AS catalyst exhibited higher activity in the total oxidation of toluene, with a toluene conversion to CO₂ and H₂O of 100% at 150 ℃. The high activity remained even at high toluene concentrations and gas hourly space velocities. The properties of the synthesized catalysts were characterized using X- ray diffraction (XRD), N₂ adsorption- desorption (Brunauer-Emmett-Teller (BET) method), transmission electron microscopy (TEM), X- ray photoelectron spectroscopy (XPS), temperature-programmed reduction of H₂ (H₂-TPR), and Fourier-transform infrared (FTIR) spectroscopy. The results showed that the Pt/TiO₂-AS crystallites were smaller than those of Pt/TiO₂-WI, with fine dispersion, greater Pt⁰ exposure on the support surface, and more active Ti―O bands, giving more oxygen vacancies and reactive oxygen species. The valence states of the active centers changed significantly (Pt⁰→Pt^δ+) during stability tests; this is the main reason for the deactivation of the Pt/TiO₂-AS catalyst.
