| Abstract: | 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. |
