Abstract:
The formation via repetitive potential cycling of a thin nickel oxy-hydroxide film on conductive Au, GC and Pt support surfaces is described. The redox and acid/base behavior and electro-catalytic activity with respect to water oxidation to form molecular oxygen of nickel oxyhydroxide thin films on gold support surfaces in aqueous base are described. A novel OER mechanism involving Ni surfaquo groups is keeping with current ideas on homogeneous water splitting is proposed. Finally the potential of the oxide modified electrode with respect to real time pH sensing is examined.
