摘要:A method for preparing a MOF of formula K 2 (M1 x M2 1-x ) 3 (Cit) 2 , where Cit is fully dehydrogenated citrate anion, M1 and M2 are metal cations of Zn, Co, Cu, Mg, Ni, Ca, Mn, Cr, Zr, and Fe, includes reacting 1 molar equivalent of citric acid with 0 to 1.0 molar equivalent of metal carbonate and/or metal oxide and 1.5 to 0.5 molar equivalent of a basic potassium compound (e.g., potassium carbonate, potassium bicarbonate and/or potassium hydroxide), where a total molar equivalent of the metal carbonate and potassium carbonate is 1.5. This step is followed by reacting with a metal salt aqueous solution. The total molar equivalent of the metal carbonate and/or metal oxide and metal acetate is 1 to 1.5. The reaction steps are conducted in DI water at a temperature below 100° C. and at ambient pressure. The MOF can be used to adsorb an acid gas from a fluid stream.
