以乙二醇为溶剂,采用溶剂热法合成了具有中空结构的4-硝基锌酞菁微球。通过扫描电镜、紫外可见光谱、BET分析及红外光谱对材料的形貌及结构特征进行了检测。结果表明,所得4-硝基锌酞菁呈独特的中空微球结构,晶相较纯,比表面积较大。同时,以罗丹明B(RB)为降解底物,在模拟可见光照条件下对材料的光催化性能及循环稳定性进行了测试,结果表明,240min后对RB的降解率达到90.86%。此外,对材料的电容性能测试表明,该材料在超级电容器电极材料方面也有较好的应用前景。
Zinc phthalocyanine (ZnPc) microspheres with hollow interior space were synthesised via solvothermal method,ethylene glycol was served as the solvent.The as-obtained product was characterized by field emission scanning electron microscopy (SEM),UV-Vis spectrum,brunauer-emmett-teller analysis,and IR spectrum.The visible light photocatalytic activity and stability of ZnPc was studied by degrading rhodamine B (RB) under visible light irrigation.The results indicated that the degradation efficiency of RB reached 90.86% in 240min.Moreover,the capacitive performance of ZnPc was also investigated,which illustrated that the obtained ZnPc microspheres would display great potential application in supercapacitor material.
