| 摘 要： | 在1-丁基-3-甲基咪唑六氟磷酸盐(Bmim]PF6)离子液体中,用微波干燥的方法制备了铁掺杂的纳米TiO2-Fe光催化剂,并以甲基橙为模拟污染物,紫外灯为光源,考察了离子液体加入量、铁掺杂量、微波干燥功率、微波干燥时间、煅烧温度、煅烧时间等因素对TiO2-Fe光催化活性的影响.结果表明:在离子液体加入量为5.6 mL,掺杂物质硝酸铁与钛酸丁酯的物质的量百分比为0.005%,于家用微波炉中在210 W功率下干燥17.5 min,再在高温箱式电阻炉中于540℃煅烧处理1.5 h后所制得的TiO2-Fe光催化剂,分别用紫外光照90 min及太阳光照射3 h后,甲基橙都几乎达到完全降解,其活性明显优于未掺杂纯TiO2的光催化活性.

| Abstract: | Fe-doped nano-TiO2 photo-catalysts were obtained by microwave drying in ionic liquids.With Methyl Orange as degradation agent and ultraviolet lamp as light source,the influence of the volume of the ionic liquid,Fe/Ti mole ratio,microwave drying power and time,calcined temperature and time on the photo-catalytic activities of Fe-doped nano-TiO2 were investigated.The results indicated that the Fe-doped nano-TiO2 catalysts showed higher photo-catalytic activity than that of pure while the Fe/Ti mole ratio was ... |
