Influence of substitution of Ru on the electrocatalytic properties of the perovskite-type LaSrNiO4 electrode towards methanol oxidation
Ru-substituted perovskite oxides with molecular formulae LaSrNi 1-xRuxO4 (0.1 ?x ?0.5) have been obtained by a modified, citric acid sol-gel route at 600C for their possible use as anodes in a direct methanol fuel cell (DMFC). These oxides have been as film on a nickel support and investigated for electrocatalysis of methanol oxidation in 1M KOH using XRD, SEM, cyclic voltammetry, chronoamperometry, impedance and Tafel polarization. The study shows that 0.2-0.5 mol Ru substitutions improve the apparent electrocatalytic activity of the oxide towards electrooxidation of methanol; the observed improvement being the greatest (? 80% at E = 0.55 V versus Hg/HgO) with 0.2 mol Ru substitution. During a chronoamperometric study of 5 h at E = 0.5 V in 1M KOH + 1M CH3OH, the Ru-substituted electrodes did not indicate any poisoning by the methanol oxidation intermediates/products. The methanol electrooxidation reaction follows a Tafel slope of ? 40 mV decade-1 and the order with respect to [OH -] is ? 2 on each electrocatalyst, regardless of the Ru content.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Product Details of 20759-14-2. In my other articles, you can also check out more blogs about 20759-14-2
