▎ 摘　　要

NOVELTY - Zr-MOFs/graphene oxide porous composite material comprises Zr-MOFs which is prepared by adding two template agents with different functions at same time, among them, template agent A is graphene oxide, which has both coordination function and carrier function with Zr-MOFs, template B is functional group that plays role in coordination competition and can be removing by washing after induction of hydrothermal reaction of Zr-MOFs. USE - Zr-MOFs/graphene oxide porous composite material. ADVANTAGE - The Zr-MOFs/graphene oxide porous composite material has simple experiment process, and improves defect degree and micropore volume of the composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing Zr-MOFs/graphene oxide porous composite material, which involves performing hydrothermal reaction synthesis of Zr-MOFs/graphene oxide porous composite material, adding zirconium tetrachloride and terephthalic acid to dimethylformamide, and then adding at certain ratio template agent A graphene oxide and template agent B, after homogeneous ultrasonic mixing, hydrothermal reaction under certain conditions, filtering and washing to obtain unactivated Zr-MOFs/ graphene oxide porous composite materials. The Zr-MOFs/graphene oxide porous composite material is activated, solvent replacement method is used to soak unactivated Zr-MOFs/graphene oxide porous composite material obtained in methylene chloride for activation treatment, after removing template agent B. The Zr-MOFs/graphene oxide porous composite material can be obtained by filtering, washing and drying.
