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.

应变稳定的氢氧化镍纳米带可实现有效的水分解
高效耐用的析氧反应（OER）催化剂的开发直接影响了水分解效率和成本效益。在这项工作中，我们报告成功合成了新的Ni（OH）2结构，应变稳定的Ni（OH）2纳米带（NR-Ni（OH）2），厚度为2至3层，宽度为2–5 nm ，通过电氧化途径。常规的Ni（OH）2通常具有可忽略的OER活性，而NR-Ni（OH）2对氧释放反应显示出高活性，并且过电势为162毫伏，并且还显示出在碱性电解质中的长期稳定性。NR-Ni（OH）2的超电势大大降低这是因为它更容易被活性四配位Ni边缘位点吸附OOH *。NR-Ni（OH）2增强的催化活性使其成为工业应用的极佳候选者。
