The invention relates to a water-stabilized
zinc-
copper metal organic frame material and a preparation method and application thereof. The water-stabilized
zinc-
copper metal organic frame material has the
chemical formula of ZnxCu1-xBIm, wherein x is smaller than 1. ZnxCu1-xBIm is shown as the
structural formula (please see the formula in the specification), wherein
zinc or
copper occupies
metal sites of ZnxCu1-xBIm. The preparation method includes the steps of firstly, mixing organic ligand BIm, Zn(NO3)2.6H2O and Cu(NO3)2 to be dissolved into DMF or the mixed
solvent of DMF and ethyl
alcohol with the volume ratio between 4 to 1 and 3 to 1, wherein the ratio of the
molar weight ratio of BIm to the total
molar weight of Zn(NO3)2.6H2O and Cu(NO3)2 is 1 to 1, the
molar ratio of Zn(NO3)2.6H2O to Cu(NO3)2 is between 99 to 1 and 85 to 15; secondly, making the materials react for 24-72 h at a temperature of 100-140 DEG C or adding auxiliaries to react to generate
solid products, cooling to the
room temperature, and conducting filtering, DMF washing and
drying. The water-stabilized zinc-
copper metal organic frame material can be used as
carbon dioxide adsorbent, has high water stability, acid stability and
thermal stability, has a high porous property, has a high BET specific surface area and high CO2 adsorption capacity, and has potential application on the aspects of the
greenhouse effect and the like.
