Energy generation through electrochemical conversion while addressing the environmental concerns has always been the topic of interest to the scientific community. Particularly, the development of low‐cost and efficient electrocatalyst gained attention for large‐scale energy and clean‐energy production. But now the emphasis is on developing low‐cost and efficient electrocatalyst materials that show more than one electrocatalytic reactions. Hence, we have developed a highly porous and active edge plane exposed β‐Ni(OH)₂ nanosheet on low‐cost and flexible stainless‐steel mesh (SSM) and investigated its catalytic activity for oxidation of urea, hydrazine, and water. The as‐prepared β‐Ni(OH)₂/SSM demonstrates the excellent catalytic activity towards the urea oxidation reaction (UOR), hydrazine oxidation reaction (HzOR), and oxygen evolution reaction (OER) with potential lower than the 1.45 V vs. RHE, 1.34 V vs. RHE, and 1.51 V vs. RHE at 50 mA/cm² current density, respectively. Furthermore, the as‐prepared electrocatalyst demonstrates excellent stability in UOR, HzOR, and OER for long time. The promising electrocatalytic activity of as‐prepared β‐Ni(OH)₂/SSM electrocatalyst is attributed to the highly porous, and edge plane exposed binder‐free thin nanosheets grown on SSM, which also adds to the mechanical structure stability and a large amount of mass transportation during electrocatalytic activity.

活性边缘位点暴露在不锈钢网上的β-Ni（OH）2纳米片作为氧化尿素，肼和水的通用电催化剂

在解决环境问题的同时，通过电化学转化产生能量一直是科学界关注的话题。特别是，低成本，高效电催化剂的开发引起了大规模能源和清洁能源生产的关注。但是，现在的重点是开发显示多种电催化反应的低成本高效电催化材料。因此，我们在低成本，柔性的不锈钢网（SSM）上开发了一种高度多孔且边缘边缘暴露的活性β-Ni（OH）₂纳米片，并研究了其对尿素，肼和水氧化的催化活性。制备的β-Ni（OH）₂/ SSM表现出对尿素氧化反应（UOR），肼氧化反应（HzOR）和析氧反应（OER）的出色催化活性，其电势分别低于RHE的1.45 V，RHE的1.34 V和1.51 V与电流密度分别为50 mA / cm ^2时的RHE相比。此外，所制备的电催化剂在UOR，HzOR和OER中具有很长的稳定性。制备的β-Ni（OH）₂ / SSM电催化剂的有前途的电催化活性归因于SSM上生长的高度多孔且边缘平面暴露的无粘结剂薄纳米片，这也增加了机械结构的稳定性和大量的电催化活性过程中的传质
