1. A preparation method of an embedded alkaline earth metal oxide solid alkali, comprising:
uniformly mixing a metal source and trimesic acid (H3BTC) in CH3COOH and H2O, crystallizing, and cooling to obtain a solid product, washing the solid product a plurality of times and drying to obtain an alkaline earth metal organic framework; and
pyrolyzing the alkaline earth metal organic framework in a non-oxidizing atmosphere to form the embedded alkaline earth metal oxide solid alkali,
wherein the metal source is selected from the group consisting of Ca(CH3COO)2, Ca(NO3)2, CaCl2, Mg(CH3COO)2, Mg(NO3)2, MgCl2, Sr(CH3COO)2, Sr(NO3)2, and SrCl2.
