Melamine-cyanuric acid supramolecular material and preparation method thereof

The invention relates to a melamine-cyanuric acid supramolecular nanosheet and a preparation method of the melamine-cyanuric acid supramolecular nanosheet. The process flow is simple, the melamine-cyanuric acid supramolecular sheet layer prepared under the control of the end-capping reagent has a nanoscale extremely small size and good crystallinity, the melamine-cyanuric acid supramolecular sheet layer can be directly pyrolyzed as a precursor to obtain nanoscale graphite-phase carbon nitride, the specific surface area of the obtained product is increased, the structural defects are reduced, the yield is increased, and the preparation method is suitable for industrial production. The final nanoscale graphite phase carbon nitride can be widely applied to wastewater purification and hydrogen preparation. 本发明涉及一种三聚氰胺-三聚氰酸超分子纳米片及其制备方法。本发明工艺流程简单，在封端剂的控制下制备的三聚氰胺-三聚氰酸超分子片层有着纳米级的极小尺寸及良好的结晶性，以其为前驱体可直接热解得到纳米级石墨相氮化碳，得到的产物比表面积升高、结构缺陷减少且产率升高，最终的纳米级石墨相氮化碳可广泛应用于废水净化和氢气制备。
