　　在室温离子液体介质中，采用溶胶-凝胶法以及微波干燥的方法制备了氮掺杂的光催化剂TiO2-N。在室温条件下，以甲基橙为模拟污染物，在微波超声波组合催化合成仪中，分别利用微波辐射（MW）、紫外光照（UV）和微波辐射-紫外光照（MW-UV）三种降解方式，主要考察了N掺杂量、微波干燥功率、微波干燥时间、煅烧温度和煅烧时间等因素对TiO2-N光催化活性的影响。结果表明，在离子液体用量为5.6 mL、N掺杂量n(N)/n(Ti)=3：1、微波干燥功率210 W、微波干燥时间20 min、煅烧温度600℃、煅烧时间2 h的条件下所制得的TiO2-N光催化剂具有较高的光催化活性；TiO2-N光催化剂在三种降解方式下对甲基橙的降解效果为：MW-UV>UV>MW，这表明微波与紫外光照有较好的协同作用，即微波-紫外光照具有强化TiO2-N催化剂降解甲基橙的效果。

N-doped nano-TiO2 photo-catalysts were prepared by microwave drying method in ionic liquid 1-butyl-3 methylimidazolium hexafluorophosphate. At a constant temperature (25℃) , using respectively the three conditions of MW, UV, MW-UV the effects of the study fo-cused on the influences of N/Ti mole ratio, microwave drying power and drying time, calcination temperature and calcination time for degrada-tion of methyl orange were investigated in the combination of catalytic synthesis of microwave ultrasonic instrument. The results indicated that the best preparing condition of TiO2-N catalyst was as follows: ionic liquid dosage 5.6 mL, n(N)/n(Ti)=3:1, microwave power 210 W, mi-crowave drying time 20 min, calcination temperature 600℃ and calcination time 2 h. And more the TiO2-N catalyst with the best preparing con-dition exhibited higher photo-catalytic activity. The degradation rate of methyl orange under three conditions were 21.2%, 95.2%, 98.7%, and degradation effect of methyl orange under three conditions: MW-UV>UV>MW. Description MW had a very good synergy with UV, microwave had the effect of strengthening N-doped nano-TiO2 degradation of methyl orange.
