The mechanism of oxygen reactions at porous oxide electrodes Part III: Water oxidation catalysis at RuO2/NiO mixed oxide electrodes
LYONS, MICHAEL; GODWIN, IAN (2014)RuO2/NiO mixed oxide electrodes prepared by thermal decomposition were examined as potential water oxidation catalysts. Addition of just 10 mol% RuO2 to a NiO electrode was found to decrease the oxygen evolution reaction ... -
Production of Ni(OH)<inf>2</inf> nanosheets by liquid phase exfoliation: From optical properties to electrochemical applications
COLEMAN, JONATHAN; DONEGAN, JOHN; NICOLOSI, VALERIA; LYONS, MICHAEL; DUESBERG, GEORG; MCEVOY, NIALL; GODWIN, IAN (2016)Here we demonstrate that liquid phase exfoliation can be used to convert layered crystals of nickel hydroxide into Ni(OH)2 nanosheets in relatively large quantities and without the need for ion intercalation. While other ... -
