摘　　要：共沉淀法合成负载型TiO_2-Nb_2O_5/丝光沸石光催化剂,以水体中苯酚的降解效果考查铌负载量对光催化剂反应活性的影响。反应条件为:室温,高压汞灯照射,催化剂投加量0.33 g/L。结果表明,Nb/Ti=0.1时光催化剂的活性最好。The TiO2 -Nb2 O5/modemite supporting photocatalyst was prepared by coprecipitation method. The effect of Nb capacity on the reactivity of photocatalytic was examined by the degradating effect of phenol in water. The reaction conditions were as follows ： room temperature, UV light irradiation, 0.33 g/L catalyst dosage. The re- sults showed that the activity of TiO2 - Nb2O5/modernite photocatalyst was the best when Nb/Ti ratio was 0.1.
