Abstract The influence of solvent used to prepare hybrid materials for photocatalytic applications formulated by cyclic bisphenol A/porphyrin copolyformal and graphene is here reported. To this purpose, the polymer is dissolved in different solvents [chloroform, tetrahydrofuran and dimethylformamide (DMF)] and used to impregnate via bath deposition 2D graphene. Depending on the nature of the solvent, polymer coats differently the graphene substrates producing peculiar SEM and AFM data. Microscopic and nanoscopic features of formulated materials were correlated with their photocatalytic activities by using methylene blue degradation test. Data collected under visible-light irradiation reveal as the best photodegradation performance was displayed by graphene coated with DMF copolyporphyrin solution. Graphic abstract

溶剂在石墨烯/聚卟啉杂化材料配方中的作用与光催化活性

摘要 本文报道了用于制备由环状双酚 A/卟啉共聚甲醛和石墨烯配制的用于光催化应用的杂化材料的溶剂的影响。为此，将聚合物溶解在不同的溶剂 [氯仿、四氢呋喃和二甲基甲酰胺 (DMF)] 中，并用于通过浴沉积 2D 石墨烯浸渍。根据溶剂的性质，聚合物以不同的方式涂覆石墨烯基材，从而产生特殊的 SEM 和 AFM 数据。通过使用亚甲蓝降解试验，将配制材料的微观和纳米特征与其光催化活性相关联。在可见光照射下收集的数据表明，涂有 DMF 共聚卟啉溶液的石墨烯显示出最佳的光降解性能。图形摘要
