Porous and/or stratified manganese oxide synthesis comprises agitating a complex-forming acid and/or its salt in a solvent, adding ammonia and/or an amine to the agitated solution and adding manganese salt solution to a oxygenated solution

摘要

The porous and/or stratified manganese oxide synthesis comprises agitating (80[deg]C) a complex-forming acid and/or its salt in a solvent. Ammonia solution and/or an amine is added to the agitated solution, and the addition is continued till the solution reaches pH of 10.5 at 25[deg]. The base solution is oxygenated to reach oxygenated potential. A divalent cation of manganese salt solution (Mn 2+) is continuously added to the oxygenated solution to precipitate the manganese oxide. The manganese oxide precipitates as Mn III xMn IV 1-x (amine H +) xO 2at a constant molar ratio (0.3-1.0).

The manganese oxide precipitates as Mn III xMn IV 1-x (amine H +) xO 2at a constant molar ratio (0.3-1.0). The complex forming acid is supplied with ammonia during a cationic buffering or with glycine, L-alanine, N-methylglycine, dimethylglycine, beta -alanine and/or asparagic acid during an anionic buffering. Independent claims are included for: (1) a manganese oxide; and (2) a device for performing the manganese oxide synthesis.
