Abstract
Two hydrotalcitelike compounds HTs were synthesized by coprecipitation The electrochemical behavior of MgZnGa Mg058 Zn017Ga025 OH2 CO32− 0125 15 H2O and ZnGaAl Zn075Ga019 Al006 OH2 CO32− 0125·15 H2O Hydrotalcitelike compounds HTs was studied in NaOH at different concentrations Voltammetric and chronoamperometric studies were performed to identify oxidation and reduction processes and the effect of the cations in total reactivity Electrocatalytic effect of HTs on hydroxide electrochemical oxidation shows better performance of MgZnGa this is apparently due to the presence of Mg and a greater amount of Ga3+ in the lattice of this HT As far as reduction is concerned ZnII reduction process is observed within the lattices of both HTs and is influenced by both the amount of OH− in the solution and the potential which the previous oxidation has been performed
