利用废旧高分子聚合物资源化制备碳氮复合光催化材料的研究

Preparation of Carbon-Nitrogen Composite Photocatalytic Materials by Recycling Waste Polymer

高分子聚合物是人类文明进步的重要标志,为人类社会的发展带来极大便利。但是,如果无法有效地回收利用废旧高分子聚合物,不仅会造成严重的环境污染,还会造成极大的资源浪费。因此,废旧高分子聚合物(PET)的循环再利用变得越来越重要。本研究以三聚氰胺与废旧塑料瓶为原料,采用高温热解碳化法,制备出三聚氰胺与PET以不同比例均匀混合的多组三维多孔碳氮复合材料。通过X射线衍射(XRD)、扫描电子显微镜(SEM),对材料的光催化降解抗生素性能进行探究,获得了光催化降解抗生素效率高达87.75%的三维多孔碳氮复合材料。

High molecular polymers are an important symbol of the progress of human civilization, bringing great convenience to the development of human society. However, if the waste polymer cannot be effectively recycled, it will not only cause serious environmental pollution,but also cause a great waste of resources. Therefore, recycling of waste high-molecular polymers has become more and more important. In this study,melamine and waste plastic bottles were used as raw materials to prepare multiple groups of three-dimensional porous carbon-nitrogen composites with melamine and PET uniformly mixed in different proportions by high temperature pyrolysis carbonization method. The composites were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM). Three-dimensional porous carbon-nitrogen composites with high photocatalytic degradation efficiency of 87.75% were obtained by exploring the photocatalytic degradation performance of antibiotics.
