Based on the fore-working, different doping rations Fe3+-TiO2 nano-material was prepared by sol-gel method ,gas-phase acetaldehyde and toluene photocatalytic degradation has been studied. There is the best Fe3+doping amount. It ' s different influences between acetaldehyde and toluene in gas-phase when H2O and O2 present. Decreasing light intensity ,the degradation of acetaldehyde and toluene both decreased. |
