Patent ID: 10518252

Abstract:
A carbon nitride membrane composite material modified by black phosphorus/metal organic framework (MOF) and a preparation method and application thereof to waste gas treatment are disclosed. First, taking urea as a raw material to calcine at a high temperature and prepare porous carbon nitride nanosheet; then carrying out surface carboxylation on the porous carbon nitride nanosheet, and modifying metal organic framework (MOF) on the surface of the porous carbon nitride through a layer-by-layer self-assembling method; stripping block black phosphorus materials into a two-dimensional black phosphorus slice by solvent exfoliation method; mixing the MOF-modified porous carbon nitride material with the two-dimensional black phosphorus material, carrying out suction filtration on the mixture under a vacuum pump to obtain the black phosphorus/MOF-modified carbon nitride membrane composite material.
