Through TiO2 nanomaterials were doped by Si on the expanded perlite which after the pretreatment in loading experiment,the effect of different acid treatment technology of expanded perlite and different Si doping amount on the properties of TiO2 nanomaterials crystallization was explored.With SEM technique,FT-IR and XRD,analysis for the morphology and hydroxylation structure of expanded perlite,the element content and phase of loaded Si doping TiO2 nanomaterials were characterized.The results shown that after concentrated sulfuric acid and hydrogen peroxide treatment,the expanded perlite produced O—H group on its surface,and when V(H2SO4)∶V(H2O2)= 42∶18,the amount of O—H group produced on the surface of expanded perlite was more.The doped Si suppressed the formation of rutile TiO2 crystal,and when the Si∶Ti=7∶1,phase of TiO2 nanomaterials was anatase type and had best crystallization performance.
