Abstract

The photodecomposition process of poly-hydroarbons on photocatalytic TiO₂ films was investigated. The in situ high-resolution transmission electron microscopy (HRTEM) was used to study the photocatalytic reaction on TiO₂ films by UV light. The decomposed hydrocarbons were composed of polymerized methane and ethylene. It was considered that the aggravated shapes and properties of the TiO₂ thin films were due to consuming of oxygen atoms in the film as an oxygen anion radical participated in the decomposition reaction.
