Significantly reducing the anodic oxidization reaction potential is very important for realizing highly efficient, energy-saving hydrogen production. In this paper, we introduce for the first time an environmentally friendly and exceptional energy-saving carbohydrazide oxidization reaction (COR) catalysis system as an anode. In this system, a robust, low-cost and valence-rich copper–iron–sulfur–oxygen porous nanocluster (Cu–Fe–S–O PN) catalyst was fabricated using a one-step mild wet chemical bath synthesis (CBS) method. Combining this catalyst and the carbohydrazide-containing electrolyte, we obtained the lowest anodic oxidization potentials ever obtained, of 0.45 V (vs. RHE) and 1.01 V (vs. RHE) for driving 10 mA cm⁻² current density in alkali or near-neutral electrolyte, respectively. These values surpass all those of previously reported environmentally friendly alkali energy-saving electrolysis systems, even neutral or near-neutral electrolysis systems, to the best of our knowledge.

低成本化合价的铜-铁-硫-氧多孔纳米簇，可在碱性和接近中性的电解质中推动出色的节能碳酰肼氧化反应

显着降低阳极氧化反应电势对于实现高效节能的制氢非常重要。在本文中，我们首次引入了一种环保且卓越的节能型碳酰肼氧化反应（COR）催化系统作为阳极。在该系统中，采用一步温和湿法化学浴合成（CBS）方法制备了一种坚固，低成本且价高的铜-铁-硫-氧多孔纳米簇（Cu-Fe-S-O PN）催化剂。。将该催化剂与含碳酰肼的电解质结合使用，可得到有史以来最低的阳极氧化电位，驱动10 mA cm ^-2时的阳极氧化电位为0.45 V（相对于RHE）和1.01 V（相对于RHE）。碱性或接近中性的电解液中的电流密度。据我们所知，这些值超过了先前报道的所有环保型碱节能电解系统，甚至中性或接近中性的电解系统。
