•Layered Mn oxides are important catalysts for water oxidation.•We used a strategy to synthesize layered Mn oxides with different ions between layers.•Ions between layers of Mn oxides are not specific for water oxidation.•Cu(II) ions decrease water-oxidizing activity of layered Mn oxides.
Here, we used a strategy to answer to the question that whether Ca(II) ion is specific for water oxidation or not? In the procedure, first we synthesized layered Mn oxides with K(I) between layers and then replaced K(I) by Ca(II), K(I), Mg(II), La(III) or Ni(II). We proposed that Ca(II), K(I), Mg(II), La(III) and Ni(II), between layers are important to form efficient water-oxidizing catalyst, but not specific in water oxidation. However, Cu(II) ions decrease water-oxidizing activity of layered Mn oxides. The result is important to find critical factors in water oxidation by low-cost and environmentally friendly nanolayered Mn oxides.
