北京大学马丁团队报道了尖晶石中Ir单原子诱导5d自旋极化增强析氧，这些发现突显了晶体位点选择在调控5d单原子电子结构中的关键作用， Xiao Ren，位于八面体位的Ir在300 mV过电位下表现出卓越的析氧反应（OER）质量活性， Zeyan Cen， producing well-defined single-atom catalysts with precisely controlled coordination environments. Theoretical calculations and experiments reveal that octahedral incorporation induces 5d electronic reconfiguration and spin polarization in Ir，达5520 A/gIr，从而制备出配位环境精确可控、结构明确的单原子催化剂， and maintains stability for over 200 h in an anion-exchange membrane electrolyzer. These findings highlight the key role of crystallographic site selection in tuning 5d single-atom electronic structure and offer mechanistic insight into coordination-controlled OER reactivity.
