Photo-Catalytic Activity of Silica Modified Anatase Nanoparticles in Hybrid Coating

One of the important commercial materials is Titanium dioxide (TiO2), which is greatly used as pigment in paints. TiO2 crystallizes in three different crystal structures, anatase,brookite, and rutile. Anatase crystal structure shows the highest photoactivity than the other phases. For offering alarge active surface area, improvement of photoactivity and a more convenient recovery, a various effort has been made on developing supported Titania catalysts. Recently, SiO2–TiO2mixed was used as not only a good photocatalyst itself but also a support material for other chemical reaction catalyst [1].At this article, TiO2-SiO2 core/shell particles were prepared from Titanium (IV) tetrabutoxide (TBT) and Tetraethylorthosilicate (TEOS) by sol-gel process and dispersed in GPTMS based sols, as inorganic-organic hybrid resins.
