Abstract
In order to consider the factors affecting the photocatalytic properties of TiO2, TiO2 powders with controlled characteristics such as the crystalline phase, the crystallite size, and the specific surface area were prepared by hydrolyzing Ti(Oi-C3H7)4. The photocatalytic property of the photo-oxidation of ethanol on the powder depended on the crystallite size and the microstructure. Ethanol was oxidized completely in the suspensions of the powders after illumination for 2 h while being bubbling with oxygen. The crystallite sizes of the powders were in the range of 20–30 nm. The microstructure of the powders consisted of the aggregation of fine and individual particles.This publication has 15 references indexed in Scilit:
