Abstract
NaFeO2 was synthesized at the condition of high temperature and strong basic environment, from which, the faint character of Fe2O3 as an acidic oxide was proved. Hypochlorite and the technique of powder-microelectrode were used to investigate the chemical and electrochemical behavior of Fe2O3, Fe(OH)3 and NaFeO2 in 14 mol/L NaOH solution, respectively. The results proved that ferrate could be made from Fe(OH)3 and NaFeO2 while Fe2O3 did not exhibit any chemical and electrochemical activity for the generation of ferrate. Furthermore, the selective electro-generation of ferrate could be realized on the electrode of NaFeO2 from 293 K to 333 K in the same solution.
