摘要
通过水热法合成掺杂非金属元素的纳米二氧化钛,以苯酚为污染源,低压汞灯为紫外光源、卤钨灯为可见光源,考察不同光降解反应条件下其对苯酚溶液的降解效果。当钛、氮和氟元素的摩尔比nTi∶nN∶nF=1∶6.5∶0.8时,经过180℃水热反应10 h,再于500℃煅烧1 h后,N-F-TiO2的光催化性能最佳。
The hydrothermal synthesis of doped with metal nanometer titanium dioxide, with phenol as a source of pollution, low pressure mercury lamp as the source of ultraviolet light, halogen tungsten lamp as the source of visible light, effects of different light degradation of phenol solution under the condition of the degradation effect, when nTi：nN：nF=l：6.5：0.8, and 180℃ for 1Oh, then calcined at 500℃ for 1 h, the photocatalytic activity of NF-TiO2 is the best.
