鉴定具有用于析氧反应的简易动力学的稳定材料是降低与从水生产氢相关的成本的重要步骤。在这项研究中，以前未开发的合金，合金L 605，其催化析氧反应的能力进行了评估，并将结果与镍200和纯钴进行了比较。合金L 605需要420 mV的过电位以实现10 mA/cm 2的电流密度。发现过电位低于镍200和钴所需的过电位。此外，合金的表面组成进行了分析，以获得洞察的催化表面。
Identifying stable materials with facile kinetics for the oxygen evolution reaction is an important step in decreasing the cost associated with the production of hydrogen from water. In this study, a previously unexplored alloy, alloy L605, was evaluated for its ability to catalyze the oxygen evolution reaction and results were compared to nickel 200 and pure cobalt. Alloy L605 required an overpotential of 420 mV to achieve a current density of 10 mA/cm2. The overpotential was found to be lower than that required for nickel 200 and cobalt. Also, the surface composition of the alloy was analyzed to obtain insight into the catalytic surface.
