| Abstract: | With TiO 2 film doping Fe prepared by sol gel process used for photocatalytic decomposition of gasoline vapour, the study on the effect of different doping ratio of Fe to TiO 2 and relative humidity shows that the optimal ratio of Fe to TiO 2 is 0.166 and the relative humidity in the reaction system has a significant effect on the decomposition of gasoline. In addition, the kinetics of gasoline decomposition was investigated, and the species formed in the decomposition reaction were characterrized. |
