具有光催化活性P(AM-AA)/CdS/TiO_2复合微球的制备研究

Study on the P(AM-AA)/CdS/TiO_2 composite microspheres with photocatalytic activity

以反相悬浮聚合法合成的P(AM-AA)微凝胶为模板,采用外源沉积法制备了P(AM-AA)/CdS复合微球,以TBOT为前驱体,通过溶胶-凝胶法制备具有光催化活性的P(AM-AA)/CdS/TiO2复合微球。结果表明,复合微球兼具有微凝胶的固有优点以及CdS和TiO2的光学性质,为进一步研究光解水制氢提供依据。

Using P （AM-AA） mierogel prepared by reverse suspension polymerization method as tern-plates, P （AM-AA）/CdS composite microspheres is prepared by exogenous deposition method. Using TBOT as precursor, the P（AM-AA）/CdS/TiO2 composite microspheres with photocatalytic activity is pre- pared by sol-gel method. The results showed that the composite microspheres has the advantages of micro- gels and photocatalytic properties of the CdS and TiO2, and it support the theory basis of photocatalytic hy- drogen production.
