摘要: 当今世界的水污染日益严重、水资源逐渐匮乏,因此开发出利用太阳光能降解水中有机污染物的催
化剂是当前研究的热点之一。以金属配位化合物为光催化剂,在可见光的照射下,研究了其对有机染料罗丹明B的
光催化降解作用。结果表明,当罗丹明B水溶液的浓度为1×10-5 mol/L、罗丹明B水溶液的体积为80mL、催化剂
质量为0.02g、反应温度为25℃、可见光功率为300W、照射时间为120min时,Co(en) 3Cl3 对罗丹明B的降解率为
87%,Ni(en) 3Cl2 对罗丹明B的降解率为2%,Ni(dien) 2Cl2 对罗丹明B的降解率为8%。因此,Co(en) 3Cl3 是性能
良好的光催化剂。

Abstract: Nowadays, the increasingly serious phenomenon of water pollution and the gradual shortage of water resources have been addressed more attentions all over the world. Developing effective catalyst for the degradation of organic pollutants in the water by using solar energy is one of the hot research topic currently. In this paper, the photocatalytic degradation of organic dye rhodamine B under visible light irradiation was studied by using metal coordination compounds as photocatalyst. The results show that the degradation rate of rhodamine B by Co(en)3Cl3 reach 87%, the degradation rate of rhodamine B by Ni(en)3Cl2 reach 2%, the degradation rate of rhodamine B by Ni(dien)2Cl2 reach 2%, under the condition of rhodamine B aqueous solution ((1×10-5mol/L) 80 mL, catalyst dosage 0.02 g, reaction temperature 25 ℃, 300 W visible light irradiation for 120 min. Thus, Co(en)3Cl3 is a good photocatalyst.
