The catalyst of nanometer Ag supported on nanomter TiO 2 particles was synthesized by irradiating TiO 2 colloid containing AgNO 3 solution.Its properties were characterized by IR,TEM,XRD,and BET methods.The size of catalyst particles was 12 1nm,composed by 95% TiO 2 and 5% Ag.The experimental results showed that the catalyst of nanometer Ag supported on nanometer TiO 2 improved obviously the activity and selectivity in the epoxidation of styrene.
