▎ 摘　　要

NOVELTY - Preparing two-dimensional metal organic framework nano material using graphene as template comprises uniformly mixing the metal salt and graphene, adding organic ligand for sealing ultrasonic treatment for 1-24 hours, washing the dry material, finally obtaining the composite material of two-dimensional metal organic framework material and the graphite, where the mass ratio of the metal salt and graphite is 1: 0.01-1:1. USE - The material is useful for electrochemical energy storage application research and water pollution treatment and gas separation. ADVANTAGE - The material has high crystalline MOF stability difference; is easy to generate accumulation; has high crystallinity; provides fast and controllable preparation of 2D nano metal organic frame material.
