Spin-state-dependent oxygen evolution activity of strained Ni–N 4 –C single-atom catalysts
Jun Zhao, Chunmei Tang, Xiaofeng Zhou, Jiangfeng Gong, Ting Xiao, Zengding Huang, Yuanyuan WangStrain engineering induces LS–HS spin-state transitions in Ni–N 4 –C. Moderate strain (4–5%) induces a high-spin state, optimizes oxygen intermediate adsorption, and reduces the OER overpotential.
