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.
