摘　　要：利用溶剂热合成技术,以三乙烯四胺为溶剂,醋酸锌和硫粉为原料,制备新型配位光催化剂[(ZnS)3(NH2CH2CH2NHCH2)2)]∞。通过红外光谱、X射线粉末衍射、透射电镜和元素分析等检测方法表征该化合物中三乙烯四胺与ZnS分子片通过配位键结合,是一种多聚结构的无机-有机杂化配位化合物。实验表明该化合物完全难溶于水、乙醇、丙酮、氯仿等有机溶剂。该化合物对活性紫(X-2R)染料溶液进行光催化降解具有较好的催化效果,催化剂经多次重复使用,催化效率基本不变,组成不变,具有良好的光催化活性。在高压汞灯照射下60 min后染料的残存率可降为20％。A novel inorganic-organic hybrid polymeric compound [ （ZnS） 3 （ NH2CH2CH2NHCH2 ） 2 ] n was synthesized by solvothermal techique from sulfur and zinc （ Ⅱ ） salt in triethylene tetramine. Detailed characterizations comfirmed the coordination of triethylene tetramine to ZnS moiety and the formation of the new compounds. The structure of the compound was characterized by IR, XRD and TEM. The compound is a stable polymer and has little solubility in water, ethanol, acetone and chloroform. The compound exhibited a considerably good photocatalytic activity in degradation of a dye reactive violet X-2R and kept nearly the same activity after 10 repeated experiments.
