Metal-organic framework nanocrystal loaded polyurethane foam as well as preparation and application thereof

The invention discloses a metal-organic framework nanocrystal loaded polyurethane foam as well as a preparation and an application thereof. Polyurethane prepolymer and active amino on MOFs (Metal-Organic Frameworks) are taken to perform chemical doping, the great challenge that MOFs materials are difficult to process is overcome, MOFs nanoparticles are uniformly loaded in the polyurethane foam, a foam reactor is obtained by means of in-situ forming, a new process of building a complex mesoporous-microporous assembly based on microporous metal-organic skeleton nanoparticles as structural units is provided to observe catalysis of the MOFs nanoparticles on knoevenagel condensation; as water serves as a foaming agent and a green chemical method is adopted to prepare an integral flow-by foam reactor to catalyze an organic reaction, aftertreatment of a catalyst is simplified, loss of the catalyst is avoided, continuous flow-by cyclic catalyzation can also be performed, and a new method is provided for the treatment of environmental pollution and chemical industry.
