Abstract

A rapid, direct synthesis of nanocolloidal silica supported copper-doped titania mesoporous particles for CO2 photoreduction was studied using a furnace aerosol reactor method. The as-prepared particles were submicrometer-sized mesoporous spheres having optimal molar percentages of TiO2 and Cu to the whole particle of 2% and 0.01%, respectively. TiO2 crystals were effectively utilized by selectively distributing them on the SiO2 mesoporous matrix surface, resulting in a relatively high CO2 conversion efficiency with a maximal CO yield of ≈ 20 μm/g -TiO2/hr. This is an abstract of a paper presented at the 103rd AWMA Annual Conference and Exhibition (Alberta, Canada 6/22-25/2010).
