▎ 摘　　要

NOVELTY - Preparing graphene/metal-organic framework porous composites hydrogel and aerogel comprises e.g. taking clean container, adding graphene or oxidized graphene dispersion, adding MOFs crystal powder, sealing container, compounding metal-organic frameworks crystal and graphene or graphene oxide obtaining graphene/metal-organic framework porous composite hydrogel, then freeze-drying to obtain graphene/metal-organic framework porous composite airgel, where mass ratio between metal-organic frameworks crystal powder and graphene or graphene oxide is 1:100-100:1. USE - The method is useful for preparing graphene/metal-organic framework porous composites hydrogel and aerogel (claimed). ADVANTAGE - The method has mild reaction conditions, simple preparation, and prevents agglomeration of graphene or graphene oxide and MOFs. DETAILED DESCRIPTION - Preparing graphene/metal-organic framework (MOF) porous composites hydrogel and aerogel comprises taking clean container, adding graphene or oxidized graphene dispersion, then adding MOFs crystal powder, sealing container, oscillating or stirring, promoting graphene or graphene self-assembled three-dimensional frame structure, and compounding metal-organic frameworks crystal and graphene or graphene oxide obtaining graphene/metal-organic framework porous composite hydrogel, then freeze-drying to obtain graphene/metal-organic framework porous composite airgel, where mass ratio between metal-organic frameworks crystal powder and graphene or graphene oxide is 1:100-100:1, graphene/metal-organic framework porous composite airgel having self-supporting porous structure and retains integrity of graphene or oxidized graphene.
