Removal of volatile organic compounds (VOCs) has recently been attracted much attention, and catalytic combustion is one of good methods for solving this problem. In this research, we show a successful preparation of mesoporous Beta zeolite-supported Pt catalyst (Pt–R/Beta-H) and its superior performance in the catalytic combustion of toluene. N2 sorption isotherms show that the mesopore volume of Pt–R/Beta-H reaches 0.18cm3/g, and TEM images exhibit that the Pt particles exist in both micropores and mesopores of the sample. Interestingly, the Pt particles on Pt–R/Beta-H have higher dispersion than the Pt particles on conventional Beta zeolite (Pt–R/Beta). XPS spectra also reveal that Pt–R/Beta-H has higher Pt0/Pt2+ ratio than Pt–R/Beta. Very importantly, Pt–R/Beta-H exhibits much higher catalytic activities and longer catalyst life as well as lower apparent activation energy in the catalytic combustion of toluene than Pt–R/Beta. The extraordinary performance in the catalytic combustion of toluene over Pt–R/Beta-H catalyst is of great importance for obtaining clean environment and enhancing human health.
