用溶胶-凝胶-表面活性剂法合成了Ag-TiO2纳米催化剂,并用FTIR、XRD、TEM、比表面测定对其进行了表征.纳米催化剂的一次粒径为5.9纳米,二次粒径为12.1纳米.实验表明,它对苯乙烯的H2O2环氧化的催化性能较好,对苯乙烯的分子氧环氧化有一定催化性能.

The catalyst of nanometer Ag s upported on nanomter TiO_2 particles was synthesized by irradiating TiO_2collo id containing AgNO_3 solution.Its properties were characterized by IR,TEM,XRD,S BET methods.The size of catalyst particles was 12 1nm,composed by 95% TiO_2 an d 5% Ag.The experimental results showed that the catalyst of nanometer Ag suppor ted on nanomter TiO_2 improved obviously the activi...
