Zusammenfassung:	The invention relates to the technical field of photocatalytic materials, and discloses a g-C3N4/PTCDI-Br composite material as well as a preparation method and application thereof. The preparation method of the catalyst comprises the following steps: reacting 3,4,9,10-perylenetetracarboxylic dianhydride, concentrated sulfuric acid, iodine and bromine to obtain bay brominated PTCDI (PTCDI-Br), calcining melamine at high temperature to obtain g-C3N4 nanosheets, and carrying out self-assembly on PTCDI-Br and g-C3N4 to obtain the composite material g-C3N4/PTCDI-Br. The composite material providedby the invention is simple in preparation process and stable in performance, has very excellent degradation capability on organic pollutants, and is an environment-friendly purification material withgreat development potential and wide market prospect. 本发明涉及光催化材料技术领域，公开了一种g-C3N4/PTCDI-Br复合材料及其制备方法和应用。该催化剂制备方法是首先将3,4,9,10-苝四酸二酐，浓硫酸，碘和溴进行反应，得到湾位溴代的PTCDI（PTCDI-Br），其次将三聚氰胺高温煅烧得到g-C3N4纳米片，最后将PTCDI-Br与g-C3N4进行自主装得到复合材料g-C3N4/P
