| Abstract: | Doped porous titania with anatase phase was prepared via thermal hydrolysis of industrial titanyl sulfate solution as titanium source,by adjusting the index of the titanium solution and the volume ratio of titanium solution to water.The as-prepared samples were characterized by XRD,particle size distribution,nitrogen absorption-desorption method and XRF determinations.Different volume ratio of titanium solution to water has great effects on the crystal structure,particle size,specific surface area and pore ... |
