The energy-saving anode with low oxidization potential has been an intriguing pursue for earth-abundant seawater electrolysis. In this paper, we first introduced a superior energy-saving carbohydrazide oxidization reaction catalysis system in the anode section, which can be driven by commercial graphite paper with good durability. Combining this catalysis reaction and common graphite paper, the lowest anodic potentials 0.63 V (vs RHE) and 1.09 V (vs RHE) were obtained for driving a 10 mA/cm current density in alkali and near-neutral seawater electrolytes, respectively, outperforming all the as-reported alkali or near-neutral seawater catalysts accordingly to the best of our knowledge.
具有低氧化电位的节能阳极一直是地球丰富的海水电解的一个引人关注的追求目标。在本文中,我们首先在阳极部分引入了一种优异的节能碳酰肼氧化反应催化体系,该体系可以由具有良好耐久性的商用石墨纸驱动。将这种催化反应与普通石墨纸相结合,在碱性和近中性海水电解质中驱动10 mA/cm²电流密度时,分别获得了最低阳极电位0.63 V(相对于可逆氢电极)和1.09 V(相对于可逆氢电极),据我们所知,相应地优于所有已报道的碱性或近中性海水催化剂。
