The boron-doped diamond (BDD) electrode, having ultra-high oxygen evolution potential and anodic stability, is potentially considered the ideal candidate for the next-generation ozone generator despite the relatively low current efficiency. In this work, we first report using a microporous BDD electrode etched by oxygen plasma, denoted as p-BDD, to improve the performance of electrochemical ozone generation. Two parameters, including O₂ plasma etching temperature and time, are experimentally optimized. We demonstrated that the electrochemically active surface area (ECSA) of the optimal p-BDD is 2.51 times that of the bare BDD, and this p-BDD shows about one-quarter lower charge transfer resistance than the latter. Under the same unit energy consumption, the p-BDD has 3.76 times the ozone generation capacity compared to the latter. The p-BDD shows excellent long-term stability, only having 4.2% of the decrease in the current density up to 40 h of consecutive water electrolysis under the steady-state period, and it also remains a 100% recovery rate in its capability of electrochemical performance after mild treatment by cycling at a diluted sulfuric acid solution for 200 s

尽管电流效率相对较低，但掺硼金刚石 (BDD) 电极具有超高的析氧电位和阳极稳定性，有可能被认为是下一代臭氧发生器的理想选择。在这项工作中，我们首先报告了使用由氧等离子体蚀刻的微孔 BDD 电极（表示为 p-BDD）来提高电化学臭氧生成的性能。两个参数，包括O ₂等离子蚀刻温度和时间经过实验优化。我们证明了最佳 p-BDD 的电化学活性表面积 (ECSA) 是裸 BDD 的 2.51 倍，并且该 p-BDD 的电荷转移电阻比后者低约四分之一。在单位能耗相同的情况下，p-BDD的臭氧产生能力是后者的3.76倍。p-BDD 显示出优异的长期稳定性，在稳态期间连续电解 40 小时电流密度仅下降 4.2%，并且在其能力方面仍保持 100% 的回收率。通过在稀硫酸溶液中循环 200 秒进行温和处理后的电化学性能
