| 摘 要： | 以中空粒子TiO2@@SiO2为载体,通过表面烷基化改性,制备出一种能漂浮于水面的界面光催化剂TiO2@@SiO2-O,并用IR,TG,接触角对其进行表征。结果表明:在无搅拌状态下,与中空粒子TiO2@@SiO2相比,界面光催化剂TiO2@@SiO2-O对罗丹明B的吸附性大大增加,其光催化效率提高了30%。

| Abstract: | Novel phase-boundary photocatalysts TiO2@@SiO2-O are prepared by modification of the surface of nanoviod TiO2@@SiO2 nanoparticles with organosilane and characterized by IR,TG and contact angle.The results illustrate that the suface-alkylsilylated nanoviod TiO2@@SiO2 nanoparticles present excellent adsorption to rhodamine B and relatively high photocatalytic activity compared with nanoviod TiO2@@SiO2 nanoparticles without mechanical stirring,and their photocatalytic efficiency increased by 30%. |
