The spectra in figures 2a and 2b are the results of the analysis of the film electrodeposited on ITO at pH 1 by the CV method (30 cycles) and dried at 60 0 C. The Mn 2p spectrum contains Mn2p3/2 and Mn2p1/2 signals located at 641,84 eV and 653,55 eV, respectively, with a spin-orbit splitting energy separation of 11,7 eV corresponding to a mixture of oxides which all are described by the formal name MnO2 , , . According to previous reports, the Mn2p3/2 spectrum exhibit pairs of peaks located at 641,93 eV and 644,90 eV, corresponding to the Mn +3 and Mn +4 species in the heterostructure , . The trivalent and tetravalent manganese are in ratios of 67,91% and 32,09%. The O1s spectrum gives important information about the forms of manganese oxides and the presence of hydrolyzed forms of manganese. We can identify the Mn-O-Mn bonds at 529,63 eV (65,53%) for tetravalent oxide, the Mn-O-H bond at 531,3 eV (18,62%) for hydrated trivalent oxide and the H-O-H bond at 532,68 eV (15,85%) for water , .
