Aiming at low adsorption rate and low adsorption capacity of volatile organic compounds (VOCs) by metal-organic frameworks (MOFs), nanoscale hierarchically porous MOFs with high VOCs adsorption rate and adsorption capacity are prepared in this project. From the theoretical point of view, the effects of crystal size and porosity property of the nanoscale hierarchically porous MOFs on the adsorption equilibrium and kinetics are discussed. Technically, the synthesis technique of nanoscale hierarchically porous MOFs is analyzed. Through the optimization of the crystal size and structure of the nanoscale hierarchically porous MOFs, the adsorption rate and adsorption capacity of VOCs are enhanced. The efficient pollution treatment of VOCs based on nanoscale hierarchically porous MOFs materials is developed. The result of this project provides theoretical basis applied technical basis for the efficient adsorption of VOCs.
