FABRICATION METHOD OF ZINC-HISTIDINE COMPLEX AND THE ZINC-HISTIDINE COMPLEX THEREBY

摘要

PURPOSE: A method for preparing a zinc-histidine complex is provided to reduce carbon dioxide emission and to prepare a catalyst which promotes conversion of carbon dioxide into bicarbonate ion. CONSTITUTION: A method for preparing zinc-histidine complex((His)_m-Zn^2+-(H_2O)_n (m=1,2,3, n=0,1,2)) comprises: a step of mixing a histidine solution and a glutaraldehyde to prepare a first mixture solution; a step of mixing a zinc acetate solution to the first mixture solution to form a second mixture solution containing the zinc-histidine complex; and a step of isolating the zinc-histidine complex((His)_m-Zn^2+-(H_2O)_n (m=1,2,3, n=0,1,2)) particles from the second mixture solution.
