The Performance of Au Nanoparticle Supported on Mesoporous TiO₂ for Low-Temperature CO Oxidation

Abstract:

A series of mesoporous TiO2 supports were synthesized by the sol-gel template method by using different surfactant and Au/TiO2 catalysts were prepared by the solution reduction method. The catalytic oxidation of CO was taken as the probe reaction for comparing the catalyst activity. Wide-angle XRD patterns and N2 adsorption–desorption isotherms revealed that the TiO2 with crystallized anatase and mesoporous structure can be synthesized after an optimized sol-gel template method. The results indicated that the pore size of TiO2 plays a key role in the catalyst activity. Among them the activity of Au/TiO2-F1 catalyst synthesized by using the F127 surfactant demonstrated superior activity to other catalysts. CO could be converted at 70 °C.
