A well-ordered mesoporous Ag / TiO_2 catalyst by in situ doping silver ions by evaporation-induced self-assembly method. The Ag / TiO_2 heterogeneous catalyst was characterized by XRD and TEM technologies.The as-made catalyst can be effectively applied in oxidative desulfurization of fuel. The Ag / TiO_2 catalyst not only exhibited higher catalytic efficiency,but also could be used repetitively for five times without a significant decrease in activity,showing a good potential in industrial applications.
