“…Os perfis voltamétricos observados são característicos de uma mistura de óxidos de Mn e são muito similares àqueles encontrados na literatura. [19][20][21] Comparando-se as curvas voltamétricas para os eletrocatalisadores constituídos de óxidos de manganês com as obtidas por Lima et al, 17 …”

“…The manganese oxide nanoparticles were chemically deposited onto the carbon substrate as follows [10,11]: 4 g of carbon was mixed with a 70 cm 3 (mL) of an aqueous solution containing 10 mmol (mM) of MnSO 4 (Aldrich). The suspension was maintained at a controlled temperature (80°C) for 20 min under magnetic stirring, in order to allow impregnation of the carbon by manganese sulphate.…”

“…Carbon-supported manganese oxides nanoparticles were found to exhibit good ORR activity in alkaline media [9][10][11][12][13]. In addition the doping of MnO x /C by the divalent ions Ni II , Mg II or Ca II , was found to be extremely promising, since the Me-MnO x /C catalysts exhibited ORR activity close to that of a benchmark Pt/Vulcan XC72 from E-Tek [12,13].…”

“…For example, the general behavior of Prussian Blue (iron hexacyanoferrate) is very similar when it is studied with carbon paste electroactive electrode (CPEE), VMP, and a thin film electrode [13]. Similarly, there is good agreement between redox cycling of MnO 2 using VMP and the compact-electrode method [14], but the VMP measurement is ten to a hundred times faster. In the voltammetry of organic microparticles, redox reactions can be either destructive, i.e., leading to a dissolution of the particle, or not, depending on the solubility of the reaction products [15].…”
