报告摘要 | Heterogeneous electrocatalysis typically involves complex multi-electron and multi-proton transfer processes, in which the interplay and competition among elementary steps critically determine catalytic activity, selectivity and stability. Notably, such chemical interplay is governed not only by intrinsic reaction thermodynamics and kinetics, but also by the evolving heterogeneous charging surface and the surrounding electric double layer. However, conventional descriptions often reduce electrochemical behavior to a static, potential-based framework, thereby overlooking the dynamic interfacial processes that define the real chemical state under operation. Using the oxygen evolution reaction as a model reaction, we have recently established a multidimensional electrochemical description framework to decouple nonlinear electrochemical responses during dynamic electrocatalytic processes. Based on this framework, we identify and track distinct anionic-site redox behavior and structural entropy compensation during the charging of non-ideal oxide surfaces, thereby establishing a correlation between charge-evolving chemical states and catalytic activity. |
