  • Development of acid-stable electrocatalysts with low overpotential for oxygen evolution reaction (OER) is a major challenge for the production of hydrogen directly from water. We report in this paper a pyrochlore yttrium ruthenate (Y2Ru2O7-δ) electrocatalyst that has significantly enhanced performance towards OER in acid media over the best-known catalysts, with an onset overpotential of 190 mV and high stability in 0.1-M perchloric acid solution. X-ray absorption near-edge structure (XANES) indicates Y2Ru2O7-δ electrocatalyst had a low valence state that favors the high OER activity. Density functional theory (DFT) calculation shows this pyrochlore has lower band center energy for the overlap betweenmore » Ru 4d and O 2p orbitals and therefore more stable Ru-O bond than RuO2, highlighting the effect of yttrium on the enhancement in stability. The Y2Ru2O7-δ pyrochlore is also free of expensive iridium metal, thus a cost-effective candidate for practical applications.« less

  • Co+Ni mixed oxides on Ni substrate were prepared through anodic electrodeposition from Co(NO{sub 3}){sub 2} and Ni(NO{sub 3}){sub 2} aqueous solutions with five different Co{sup 2+}/Ni{sup 2+} ratios beside only Co{sup 2+}. By the electrochemical measurements, the optimum performance in electrocatalytic activity for oxygen evolution reaction in alkaline media was obtained on the Co+Ni mixed oxide deposited from the solution containing Co{sup 2+}/Ni{sup 2+} ratio of 1:1. The mixed oxide is corresponding to about 68at% Co contents with spinel-type NiCo{sub 2}O{sub 4} phase and porosity surface structure. The electrochemical kinetic parameters including exchange current density, Tafel slopes, reaction order withmore » respect to [OH{sup -}] and standard electrochemical enthalpy of activation were analyzed also. A possible mechanism involving the formation of a physisorbed hydrogen peroxide intermediate in a slow electrochemical step was presented, which accounts for the values of the experimental results.« less
