Abstract:
1. A manufacturing method of making an iron oxide through an iron complex, comprising: a chelating step mixing a ferric chloride, first chelating agent and second chelating agent with a solvent to form an iron complex solution, wherein the first and second chelating agents are selected from a group consisting of ethylenediamine, 1,10-phenanthroline, 2,2′-Bipyridine, diethylenetriamine, triethylenetetraamine, phenanthroline, and bipyridine, and Fe a drying step removing the solvent from the iron complex solution to obtain a dried iron complex; and a heat treatment step executing heat treatment for the dried iron complex to form iron oxide with molecular formula Fe wherein the iron complex is in the form of Fe[R
