摘　　要：通过高聚物固体电解质Nafion分隔阴、阳极,将TiO_2光催化剂负载在活性碳/石墨载体和泡沫镍载体上,构成新型气相光电催化反应系统。制造的微多孔光催化层使催化剂活性大大增加。气相光电催化反应系统降解环己烷的效率比单独光催化、电催化都高。实验结果表明,当两种载体涂层数均为3层,水蒸气与环己烷比率为20:1,外加电压为20V时,反应降解效率最高。A novel system of gas phase-photoelectrocatalysis is designed with high polymer solid electrolyte Nation separating anode and cathode and then TiO2 film being loaded on an active carbon/graphite sheet or a porous nickel as anode and cathode. The degradation efficiency of photoelectrocatalysis is higher than that of the single photocatalysis or electrocatalysis. The experimental results show that the highest degradation efficiency is obtained when the coating layers of TiO2 are 3, the volume ratio between water vapor and cyclohexane is 20： 1 and the applied potential is 20V.
