摘　　要：以对苯二酚-二[2,3(3,4)-二氰基苯基]醚、邻苯二腈(4-苯氧基邻苯二腈、4-硝基邻苯二腈)、硝酸钴及氢氧化锡为原料原位合成了系列酚氧基桥连的双核CoPc/SnO_2复合材料,通过红外光谱、紫外-可见分光光度计、X射线衍射及热重等手段对目标产物进行了表征,确定了复合材料的基本结构。同时,考察了各种复合材料对罗丹明B的催化降解能力。结果表明:各种复合材料对罗丹明B均具有较好的催化降解效果,酞菁外围取代基的类型及桥连基团在酞菁环上位置对催化降解都会产生影响。A series of binuclear CoPc/SnO_2 composite material linked by phenol oxygen radicals were synthesized by in-situ method,while hydroquinone-di[2,3（3,4）-dicyanophenyl]ether,phthalonitrile（3-nitro phthalonitrile,4-nitro phthalonitrile）,cobalt nitrate and tin hydroxide were selected as raw materials.The target products were characteristiced by FT-IR,UV-Vis,XRD and TG method.The basic structure of composite materials were determined.At the same time,the catalytic degradation ability of various composite materials to rhodamine B were examined.The results showed that all kinds of composite materials had good catalytic degradation effect on rhodamine B.The catalytic degradation efficiency can be influenced by peripheral substituents of phthalocyanine and position of bridging groups in phthalocyanine.
