METHOD FOR PREPARING ZINC-HISTIDINE SELF-ASSEMBLY BIOMIMETRIC COMPLEX, ZINC-HISTIDINE SELF-ASSEMBLY COMPLEX PREPARED BY SAID METHOD, AND METHOD FOR REDUCING CARBON DIOXIDE USING SAID ZINC-HISTIDINE SELF-ASSEMBLY COMPLEX

摘要

Method for preparing zinc-histidine self-assembly biomimetic complex activating reaction to convert carbon dioxide into bicarbonate ion, zinc-histidine self-assembly biomimetic complex by preparation method, and method for reducing carbon dioxide using zinc-histidine self-assembly biomimetic complex. The preparation includes: mixing L-histidine and p-toluene sulfonic acid in first organic solvent to form first mixed solution and recrystallizing first mixed solution with ethyl ether to prepare first mixed substance: mixing first mixed substance with azelaic acid in second organic solvent to form second mixed substance containing imidazole and amide groups; mixing second mixed substance with NaOH and HCl in third organic solvent to form third mixed solution and recrystallizing third mixed solution with ethyl ether to prepare third mixed substance having amphiphilic characteristic: and mixing third mixed substance with aqueous solution of zinc precursor and causing self-assembly to prepare zinc-containing self-assembly biomimetic complex.

1. A method for preparing a carbonic anhydrase-mimetic self-assembly complex, comprising:
(a) mixing L-histidine and p-toluene sulfonic acid in a first organic solvent to form a first mixed solution and recrystallizing the first mixed solution with ethyl ether to prepare a first mixed substance; (b) mixing the first mixed substance with azelaic acid in a second organic solvent to form a second mixed substance containing an imidazole group and an amide group; (c) mixing the second mixed substance with sodium hydroxide (NaOH) and hydrochloric acid (HCl) in a third organic solvent to form a third mixed solution and recrystallizing the third mixed solution with ethyl ether to prepare a third mixed substance having an amphiphilic characteristic; and (d) mixing the third mixed substance of the step (c) with an aqueous solution of a zinc precursor and causing a self-assembly to prepare a zinc-containing self-assembly biomimetic complex.
