Preparation and Properties of Ag –TiO2-SiO2 composite photocatalyst
abstract:we prepared Silica Microspheres as a nuclear by the classic stober ( sol - gel ) method; with phthalic acid butyl ester as the raw material ,prepared core-shell particles of TiO2-SiO2 by the sol - gel method ,With silver mirror method to silver -doped.Sub methyl blue for Target degradation,studied The photocatalytic activity.Experimental results showed that the catalytic activity of core-shell particles of TiO2-SiO2 what modified by Ag increased by 2.5 times Significantly.characterized by XRD , TEM and other means.The results showed that the composite particles of silver doped some photocatalytic methylene blue degradation exhibited excellent activity .
Keywords : stober , ; silica ; sol - gel method ; silver doped
