摘 要: | 选用掺杂锌的纳米TiO2作为光催化剂对亚甲基蓝进行降解研究。制备工艺参数对样品光催化降解亚甲基蓝的活性具有很大影响,焙烧温度为500℃,Zn2+掺入量为0.5%,催化剂的加入量为1 g/L时光催化剂对亚甲基蓝的降解效果最好;亚甲基蓝的初始浓度为5 mg/L降解速率较快。

Photocatalytic degradation of methylene blue solution by TiO2 particles Zn2+-doped |

Abstract: | Methylene blue solution was degraded by TiO_2 particles doped Zn~(2+) as photo-catalyst. Parameters during preparation of the catalyst affected the photocatalytic degradation rate of methylene blue greatly. The photocatalytic degradation rate of methylene blue was the highest when calcining temperature was 500℃, incorporation of Zn~(2+) was 0.5% ,dosage of catalyst was 1 g/L. The degradation was faster when initial concentration of methylene blue was 5 mg/L. |
