摘要
氧化石墨烯(GO)因其独特的物理化学性质,已被广泛应用于能源材料、太阳能电池和催化反应等领域。制备了5,10,15,20-四苯基卟啉锌/氧化石墨烯复合材料(ZnTPP/GO),通过紫外-可见吸收光谱(UV-vis)、透射电子显微镜(TEM)、荧光发射(PL)等手段对该复合材料进行了表征,并研究了该复合材料对罗丹明B的光降解性能。结果表明,在可见光下该复合材料对罗丹明B溶液具有较好的光催化降解效果。该研究为进一步提高光降解有机污染物的性能提供了有价值的参考。
Graphene oxide(GO) has been widely used in energy materials, solar cells and catalytic reactions due to its unique physical and chemical properties. In this study, the zinc(Ⅱ) 5,10,15,20-tetraphenylporphyrin/graphene oxide composite(ZnTPP/GO) was prepared. And the composite was characterized by ultraviolet-visible absorption spectroscopy(UV-vis), transmission electron microscopy(TEM) and fluorescence emission(PL). The performance of the composite for the photodegradation of Rhodamine B was studied. The results showed that the composite had good photocatalytic degradation performance under visible light. This study can provide valuable reference for photodegradation of organic pollutants.
