摘要/Abstract

摘要： 通过对石墨相氮化碳(g-C₃N₄)进行形貌调控来提高其光催化性能,并探索其在骨关节炎的抗氧化治疗方面的潜在应用.以三聚氰胺和三聚氰酸为前驱体,采用改良的超分子自组装热聚合法,成功制备出了形貌规则的花状g-C₃N₄.借助透射电子显微镜(TEM)、X射线衍射(XRD)等手段对材料形貌与结构进行表征;通过紫外-可见漫反射光谱(DRS)、光致发光光谱(PL)及光催化产氢测试来评价其光学与催化性能,并且进一步进行体外活性氧(ROS)清除实验.结果表明:与传统块状g-C₃N₄相比,所合成的花状g-C₃N₄具有规则的形貌、较强的光吸收能力,其光催化产氢效率达到块状g-C₃N₄的3倍,还能有效清除过量ROS.综上,花状g-C₃N₄不仅是一种高效的光催化产氢材料,而且在骨关节炎等炎症相关疾病的抗氧化治疗中展现出良好的应用前景.
