Abstract
High Resolution Image Download MS PowerPoint Slide Facilitating the kinetically demanding oxygen evolution reaction (OER) is essential for the sustainable conversion of renewable energy into chemical fuels. However, precisely unraveling the dynamics of active species and sites during the OER remains a significant challenge. Herein, we constructed a series of Co-substituted Ni coordination polymers (Ni-CPs) for the OER. Complementary surface-/bulk-sensitive operando time-resolved spectroscopic monitoring enables detailed mechanistic insight into the critical role of partial Co incorporation in modulating the local coordination geometry of Ni centers and thereby promoting the intrinsic OER kinetics. Our results…
