摘要：

Interfacial reactivity is the central concern in wide range of application, particularly, in field of heterogeneous catalysis, which is essentially the foundation of battery and energy applications. As such, capability of interfacial electrochemical property tailoring is critical in device performance optimization. Conventional approaches often gauge the problem based on the manipulation of the chemical composition of the catalyst or electrode material, additionally, the limitation of existing analytical techniques are often good in solid state sample characterization but poor in solution phase probing, leading to the overlooking of the impact from the solution structure. In this work, we present a force spectroscopy approach to characterize the hydrogen evolution reaction from solution phase structuring of electric double layer perspective. Our results demonstrate that merely the manipulating the solution phase structuring can effectively alter the reactivity of the reaction, creating a new field in gauging reactivity apart from electrode material design.
