摘要

阐明和调节催化剂的动态重构对各种电催化反应至关重要。在这里,我们应用模型拟合和操作表征来量化层状 Co(OH)2 在氧进化反应(OER)中的重构活性(即重构能力)。通过调节 Co(OH)2 中的插层物种,我们控制了不同的重构热力学和动力学,在 OER 过程中出现了不同的质量变化和异质 Co 氧化。我们进一步确定了重构活性与 OER 活性之间的火山型关系,并发现通过双阴离子插层实现的适度重构活性有利于提高 OER 活性。这可能是由于其适当的基底间距调节了离子(脱)插层-电子转移的耦合重构,从而使结合 OER 中间体的 Co 达到最佳状态。最佳重构的 Co(OH)1.26Cl0.08(CO3)0.33-0.84 H2O 可在 1.78 V 电压下提供 1 A cm-2,用于阴离子交换膜电解水。这项工作为调节重构活性以促进电催化奠定了基础。

Regulating Reconstruction Activity of Cobalt Electrode for Optimized Water Oxidation

Regulating Reconstruction Activity of Cobalt Electrode for Optimized Water Oxidation

Elucidating and regulating dynamic catalyst reconstruction are crucial for various electrocatalytic reactions. Here, we applied model fittings with operando characterizations to quantify the reconstruction activity (i.e., ability to reconstruct) of layered Co(OH)2 toward the oxygen evolution reaction (OER). By modulating the intercalation species into Co(OH)2, we governed distinct reconstruction thermodynamics and kinetics, with diverse mass changes and heterogeneous Co oxidation during the OER. We further established a volcano-type relationship between reconstruction activity and OER activity and identified that a moderate reconstruction activity, achieved by dual-anion intercalation, favored a high OER activity. This might result from its proper basal spacing that regulated the coupled ion (de)intercalation–electron transfer for reconstruction, leading to optimal Co for binding OER intermediates. The optimally reconstructed Co(OH)1.26Cl0.08(CO3)0.33·0.84 H2O delivered 1 A cm–2 at 1.78 V for anion-exchange membrane water electrolysis. This work laid the foundation for modulating reconstruction activities to benefit electrocatalysis.
