摘要
采用对苯二甲醛和二硫代乙酰胺为原料,在DMF溶剂中加热回流的条件下合成了聚(苯噻唑并[5,4-d]噻唑)(p-PhTT)有机多孔聚合物。利用X射线衍射仪、扫描电子显微镜、红外光谱仪、紫外-可见漫反射光谱仪、氮气吸脱附测试、电子顺磁共振光谱等对p-PhTT的结构、化学组成、微观形貌和光学性质进行了表征,并以罗丹明B为模拟污染物进一步探讨了p-PhTT在可见光照射下的光催化降解性能。实验结果表明,在可见光照射60 min后,罗丹明B降解率达到了98%,循环降解实验证明p-PhTT具有良好的化学稳定性,在有机污染物废水处理中具有潜在的应用前景。
Porous poly(phenylene-thiazolo[5,4-d]thiazole)(p-PhTT)polymer was synthesized using terephthalaldehyde and dithioacetamide as raw materials under refluxing in DMF.The structure,chemical composite,morphology and optical property of p-PhTT were characterized by X ray diffraction,scanning electron microscopy,infrared spectroscopy,ultraviolet-visible diffuse reflectance spectroscopy,nitrogen adsorption and desorption measurements,electron paramagnetic resonance spectroscopy.The photocatalytic performance was investigated by photocatalytic degradation of rhodamine B under visible light irradiation.The results showed that the degradation rate of rhodamine B reached 98%after 60 min under visible light irradiation and the cyclic degradation experiments demonstrated good chemical stability.The resulting p-PhTT material possessed a potential application in the treatment of wastewater containing organic pollutants.
