The study examines the oxygen evolution reaction (OER) electrocatalytic efficiency of various stainless‐steel mesh (SSM) sizes in electrolytic cells. Stainless steel is chosen due to its widespread availability and stability, making it an economically viable option. The primary objective of this investigation is to determine the optimal stainless‐steel mesh size among those currently widely available on the market. The classification of stainless‐steel mesh sizes as SS304 is confirmed by the minimal compositional variations observed across all mesh sizes through cyclic voltammetry (CV) and X‐ray fluorescence (XRF) analyses. Remarkably, CV experiments carried out at different scan rates indicate that SSM 200 has the maximum specific electrochemical surface area (ECSA). As a result, SSM 200 demonstrates superior performance in terms of current density response and shows the lowest overpotential in the alkaline medium compared to other stainless‐steel mesh sizes. Stability tests conducted under constant voltage further confirm the remarkable stability of SSM 200, making it an ideal anode for electrolytic cell applications. These findings emphasize the cost‐effectiveness and high stability of SSM 200, presenting intriguing possibilities for future research and advancements in this field.

用于电化学析氧反应的商用不锈钢网尺寸的确定

该研究检查了电解池中各种不锈钢网（SSM）尺寸的析氧反应（OER）电催化效率。选择不锈钢是因为其广泛的可用性和稳定性，使其成为经济上可行的选择。本次调查的主要目的是确定目前市场上广泛使用的不锈钢筛网尺寸的最佳值。通过循环伏安法 (CV) 和 X 射线荧光 (XRF) 分析，观察到所有网孔尺寸的成分变化极小，从而确认了不锈钢网孔尺寸的分类为 SS304。值得注意的是，在不同扫描速率下进行的 CV 实验表明 SSM 200 具有最大的电化学比表面积 (ECSA)。因此，与其他不锈钢网尺寸相比，SSM 200 在电流密度响应方面表现出卓越的性能，并且在碱性介质中显示出最低的过电势。在恒压下进行的稳定性测试进一步证实了 SSM 200 卓越的稳定性，使其成为电解池应用的理想阳极。这些发现强调了 SSM 200 的成本效益和高稳定性，为该领域的未来研究和进步提供了有趣的可能性。
