Abstract: Presents a thermodynamic study based on the phase diagram of the Na[sub2]O-MnO-Fe[sub2]O[sub3] system for the production of hydrogen in water splitting. Background on hydrogen energy; Observation of sodium iron manganese oxides at a certain point of the phase diagram; Discussion on the phase where the oxides were observed.
