| 摘 要： | 用溶胶-凝胶法制备了锆改性纳米二氧化钛光催化剂，并用XRD、UV-vis、BET等测定技术对所制得的粉体试样进行了表征。同时以甲基橙及苯酚为模拟污染物，评价了改性后纳米二氧化钛的光催化性能，发现其光催化活性大大高于未改性二氧化钛粉体，并得出当n（Zr）／n（Ti）=5／300时，锆改性纳米二氧化钛样品的光催化活性最高。

| Abstract: | Nanosized TiO_2 particles modified by Zr have been prepared by a solgel method.The nanosized particle are characterized by UVvis,XRD and BET measurements.The photocatalytic activity of modified TiO_2 particles is evaluated using methyl orange aqueous solution and phenol as simulating pollutants.The results show that the photocatalytic reactivity of TiO_2 modified by Zr is much higher than that of unmodified TiO_2 and it is the highest when the optimal ratio is n(Zr)/n(Ti)=5/300. |
