β_2-SiW_(11)Co/四丁基溴化铵电荷转移配合物的合成及光催化性能

Sythesis and Photocatalytic Activity of β_2-SiW_(11)Co and Tetrabutylammonium Charge-transfer Complex

以β2-SiW11Co/TBA为光催化剂,在紫外灯辐射下,研究了其对模拟染料废水亚甲基兰蓝溶液的光催化降解的反应,考察了催化剂投加量、染料浓度、pH对亚甲基兰降解率的影响。结果表明,亚甲基兰溶液光催化降解的最佳条件为:pH=4,β2-SiW11Co/TBA催化剂投加量为0.15 g.L-1,染料浓度为8 mg.L-1,经30 W紫外灯照射150 min后,其降解率为92.91%。

The β2-SiW11Co/TBA was researched as the photocatalyst to degradation of the methylene blue in solution under the UV ray. The influences of several operating parameters, such as the dosage of catalyst, initialdye concentration, and pH, on the photocatalytic degradation of methylene blue were investigated. The degradation rate of methylene blue With ,β2-SiW11Co/TBAwas 92.91% after being treated for 150 min under 30 W ultraviolet light irradiation at pH 4, using 0.15 g.L-1.
