Abstract

A simple and efficient approach to produce highly active nanocrystalline SO4(super 2-)/TiO2-SiO2 is reported and the favorable synergetic effects between sulfate species and silica in enhancing its photocatalysis efficiency is revealed. The results revealed that for SO4(super 2-)/TiO2 and TiO2-SiO2 the sole presence of either sulfate species or silica imposes negative effects on the photocatalysis behavior of titania, leading them to have negligible photoactivities.

Abstract

A novel, simple, and effective method to produce highly active sulfate-promoted rutenile TiO(sub 2) that can be efficiently operated in the visible light region by an in situ sulfation method is successfully developed. The results show that sulfate species are sensitive to the variation of calcination temperature.
