An abundant, highly active, and durable oxygen evolution reaction (OER) electrocatalyst is an enabling component for a more sustainable energy future. We report, herein, a molybdenum and niobium codoped B-site-ordered double perovskite oxide with a compositional formula of BaCoMoNbO (BCMN) as an active and robust catalyst for OER in an alkaline electrolyte. BCMN displayed a low overpotential of 445 mA at a current density of 10 mA cm. BCMN also showed long-term stability in an alkaline medium. This work hints toward the possibility of combining a codoping approach with double perovskite structure formation to achieve significant enhancement in the OER performance.
一种丰富、高效且耐用的氧析出反应 (OER) 电催化剂是实现更可持续能源未来的关键组成部分。我们在此报告了一种钼和铌共掺杂的 B 位有序双钙钛矿氧化物，其分子式为 BaCoMoNbO（BCMN），作为碱性电解质中 OER 的活性和坚固的催化剂。BCMN 在 10 mA cm 的电流密度下表现出 445 mA 的低过电势。BCMN 在碱性介质中也表现出长期稳定性。这项工作暗示了将共掺杂方法与双钙钛矿结构形成相结合以实现 OER 性能显著提高的可能性。
