摘　　要：采用溶胶-凝胶法,以钛酸丁酯为原料制备纳米级二氧化钛,将其负载于采用化学沉淀法以九水硝酸铁为原料制备的针铁矿上,对复合材料进行透射电镜分析,确定了制备的最佳影响因素,将2种溶胶进行复合提膜,研究其光催化效率。The aim of this dissertation is to synthesize nanometer Titania sol through the hydrolysis of Ti with the method of sol-gel. Loading it on goethite sol which was prepared through ferric nitrate ninehydrate with the method of chemical precipitation and taking TEM analyses of the composite, the best synthesize factor of the composite was obtained. The film of the two composite sol was established to study the photocatalyst efficiency.

关 键 词：溶胶-凝胶法 化学沉淀法 纳米二氧化钛与针铁矿的复合膜 光催化
