Abstract

Development of efficient and durable oxygen evolution reaction (OER) catalysts has a direct impact on the water splitting efficiency and cost effectiveness. In this work, we report the successful synthesis of a new Ni(OH)₂ structure, strain-stabilized Ni(OH)₂ nanoribbons (NR-Ni(OH)₂) two to three layers thick, with widths of 2-5 nm, via an electro-oxidation route. Conventional Ni(OH)₂ usually has negligible OER activity, while NR-Ni(OH)₂ shows high activity for the oxygen evolution reaction and an overpotential of 162 millivolts and furthermore exhibits long-term stability in alkaline electrolyte. The substantial reduction in the overpotential of NR-Ni(OH)₂ is due to its easier OOH∗ adsorption by the active four-coordinated Ni edge sites. The enhanced catalytic activity of NR-Ni(OH)₂ makes it an excellent candidate for industrial applications.
