Abstract
TiCl4, ammonia, inorganic salts as raw material, nanometer composite-crystal TiO2 powders were synthesized by two-step chemical method. Precursors were crystallized with different phase and stable composite-crystal TiO2 with anatase and rutile phase was prepared at low temperature. Quantitative control of crystal phase was realized. Remarkable factors including reaction pH value, reaction time, which affected the phase content, microstructure, morphology were discussed. Applied experiments of photo-degradation organic dyes illuminated by sunshine showed higher photocatalytic activity of composite-crystal than that of pure anatase, pure rutile and mechanical mixture of both, nanometer composite-crystal TiO2 as photocatalyst.
