Enhancing acidic oxygen evolution reaction with a highly stable Eu-doped RuO 2 electrocatalyst
Yin Qin, Kang Jie Li, Zilin Yan, Zhehan Ying, Kaikai Li, Hao Xiang Li, Tong-Yi ZhangEu's 4f buffer band stabilizes the Ru–O covalent bond through 4f–2p–3d gradient orbital coupling, thereby suppressing Ru oxidation and dissolution in PEM-WE.
