Assessing materials’ stability under operating conditions is of critical importance to the development of device-oriented electrocatalysts, but few efforts have been devoted to this on a large scale. In this work, using the Materials Project data, we explore the aqueous stability of 47 814 nonbinary metal oxides under typical oxygen reduction/evolution reaction conditions and identify 68 likely acid-stable candidates for oxygen electrocatalysts. We also construct an “acid-stable periodic table” to guide the search for new acid-stable materials for electrocatalysis.

氧电催化酸稳定的氧化物

评估材料在工作条件下的稳定性对于开发面向设备的电催化剂至关重要，但是在大规模开发方面却很少有努力。在这项工作中，使用材料项目的数据，我们探索了在典型的氧还原/演化反应条件下47 814种非二元金属氧化物的水稳定性，并确定了68种可能的酸稳定型氧电催化剂。我们还构建了“耐酸元素周期表”，以指导寻找用于电催化的新耐酸材料。
