Abstract

Surface science studies of electrochemical interfaces and processes have gained increasing popularity in the last decades, owning to the increasing importance of electrochemistry for key technologies of the 21th century, especially in electric energy storage and conversion. In situ and operando surface-sensitive methods, such as scanning probe microscopy and surface X-ray diffraction, as well as complementary ab initio theory can provide atomic-scale information on solid electrode surface in contact with liquid electrolytes, including structural changes under reaction conditions. The level of detail obtainable by these approaches is illustrated in this short review for selected examples. These include the adsorption of sulfate and other oxyanions, where a crucial role of coadsorbed water is found, the restructuring of Cu electrode surfaces under hydrogen evolution and CO2 reduction conditions, and the mechanisms of electrochemical Pt oxidation and its correlation with Pt dissolution.

电化学表面科学的兴起:从原位界面结构到操作动力学
过去几十年来,由于电化学在 21 世纪关键技术(尤其是电能存储和转换技术)中的重要性与日俱增,有关电化学界面和过程的表面科学研究越来越受欢迎。扫描探针显微镜和表面 X 射线衍射等原位和操作表面敏感方法,以及互补的 ab initio 理论可以提供与液态电解质接触的固体电极表面的原子尺度信息,包括反应条件下的结构变化。本简短综述将举例说明这些方法所能获得的详细程度。这些例子包括硫酸根离子和其他氧阴离子的吸附(其中共吸附水起着关键作用)、氢气进化和二氧化碳还原条件下铜电极表面的结构重组,以及电化学铂氧化机制及其与铂溶解的相关性。

期刊介绍: Surface Science is devoted to elucidating the fundamental aspects of chemistry and physics occurring at a wide range of surfaces and interfaces and to disseminating this knowledge fast. The journal welcomes a broad spectrum of topics, including but not limited to: • model systems (e.g. in Ultra High Vacuum) under well-controlled reactive conditions • nanoscale science and engineering, including manipulation of matter at the atomic/molecular scale and assembly phenomena • reactivity of surfaces as related to various applied areas including heterogeneous catalysis, chemistry at electrified interfaces, and semiconductors functionalization • phenomena at interfaces relevant to energy storage and conversion, and fuels production and utilization • surface reactivity for environmental protection and pollution remediation • interactions at surfaces of soft matter, including polymers and biomaterials. Both experimental and theoretical work, including modeling, is within the scope of the journal. Work published in Surface Science reaches a wide readership, from chemistry and physics to biology and materials science and engineering, providing an excellent forum for cross-fertilization of ideas and broad dissemination of scientific discoveries.
