商业电解设备的高效水分解是基于材料的发展，特别是催化电极，表现出活性和稳定性之间的最佳平衡。电催化材料，特别是酸性聚合物电解质膜电解槽中的出氧阳极，其活性和稳定性之间的反比关系使其发展复杂化。本文展示了一种用于低ph水裂解的纳米结构析氧反应（OER）电催化剂的开发。采用混合铷硼化物脱合金制备高纵横比电催化材料，其OER过电位低，与钌氧化物相当，电解稳定性与铁氧化物相当。图形抽象
Efficient water splitting for commercial electrolysis devices is predicated on the development of materials, specifically for the catalytic electrodes, that exhibit an optimal balance between activity and stability. Complicating the development of electrocatalytic materials, particularly for oxygen-evolving anodes in acidic polymer electrolyte membrane electrolyzers, is an inverse relationship between activity and stability. Here the development of a nanostructured oxygen evolution reaction (OER) electrocatalyst for low-pH water splitting is demonstrated. Dealloying of mixed RuIr borides is used to form a high aspect ratio electrocatalytic material that exhibits low OER overpotentials matching that of RuOxand electrolytic stability matching that of IrOx.Graphic abstract
