硅铝固载TiO2介孔材料的水热合成及光催化性能研究
Study on hydrothermal preparation of TiO2 mesoporous materials with silica-alumina carrier and their photocatalytic property
摘要
Abstract
With Na2 SiO3 ,Ti(SO4 )2 and Al2 (SO4 )3 as starting reactants ,a set of mesoporous photocatalytic TiO2 materials (TiO2/MSA) with SiO2/TiO2 mole ratio of 1∶0 .05~0 .7 and with silica‐alumina carrier were prepared through hydrothermal method prior to final calci‐ning procedure in this paper .By means of small angle XRD ,TEM and FT‐IR measurements , the microstructure and the mesoporous configuration of the final products were examined and characterized .The effects of TiO2 loading amount ,pH value and sintering temperature on mesoporous configuration and photocatalytic performance were also investigated .The ob‐tained results show that the final TiO2/MSA materials have well‐crystalline anatase octo‐hedrite structure which is promoted with the increase of the TiO2 amount loaded .The meso‐porous configuration and photocatalytic properties are firstly strengthened and then weak‐ened with the increase of sintering temperature and the amount of TiO2 loaded .It also shows that acidic conditions is suitable to the formation of anatase crystals and to the enhancement of photocatalytic properties .关键词
