中文摘要：
研究了四针状氧化锌晶须在紫外光照射条件下对甲基橙的降解活性,考查了甲基橙溶液初始浓度、催化剂浓度及种类等对光催化降解的影响,并初步探讨了其反应动力学。实验结果显示,四针状氧化锌晶须光催化降解反应基本符合一级动力学规律,光催化效果随着甲基橙初始溶液浓度的增加而降低,最佳浓度为2g/L,是一种降解效果优异的光催化材料。
英文摘要：
The photocatalytic degradation of methyl orange by T-ZnO whiskers was researched under the UV- light irradiation. The effects of the initial concentration of methyl orange, the concentration of the photocatalyst, the species of the photocatalysts and the degradation kinetics were investigated. The results of the experiments show that the photocatalytic activation of T-ZnO whiskers accords with the rule of first-order reaction, and the optimal concentration of T-ZnO whiskers is 2g/L. The experiments also indicated that the T-ZnO whisker is a good photocatalyst, which appears better effect than that of the nano-TiO2.
