摘要：Objective: to determine the optimum preparation conditions and the treatment effect of TiO2/GF photo catalyst by four factors and three horizontal orthogonal tests. Methods: the preparation of sol-gel immersion Fe, N total light catalyst, doping TiO2 / GF in homemade photo catalytic reactor, based on nitrobenzene degradation rate, design and discusses the calcination time, calcination temperature, Fe doping amount and N doping amount of light the influence of catalyst preparation and its physical and chemical properties. Results: the results showed that the main order of influence was: >Fe doping, >N doping, > calcination time; The catalytic activity of co-doped photo catalyst is better than that of single doped TiO2 catalyst. Conclusion: the best preparation conditions as follows: 2.5 h calcination time, calcination temperature 550 °C, Fe doping amount 0.5% (mass fraction) and N doping amount is 0.45% (mass fraction), deal with 40 mg/L of nitrobenzene degradation, nitrobenzene wastewater degradation rate was 86.5%. The catalyst can be reused.
