摘要

原位光谱方法的发展使得在活跃的电化学条件下对电极和/或电催化剂的表面化学和结构进行了详细的研究，提供了对电极-电解质界面反应途径的实时洞察，这对于理解能源装置中的电化学过程是必不可少的。了解能量反应催化剂的高电化学选择性和活性的关键挑战包括测量反应动力学，检测化学环境的变化，识别反应中间体，以及将材料特性与设备性能联系起来。本文综述了傅立叶变换红外、拉曼、x射线吸收和x射线光电子能谱等各种原位和operando光谱方法在可充电锂离子电池、超级电容器、水分解（O2和H2演化）、混合电解与小分子氧化成氢燃料和增值化学生产中的先进应用。强调各种原位/操作方法在优化催化剂设计、提高能量储存和转换效率和耐久性方面的重要性，我们系统地评估了它们在解决能源材料研究中的主要挑战方面的作用，总结了它们的运行机制、优点和局限性，并为未来的实验策略提供了指导。

In situ Spectroscopy: Delineating the mechanistic understanding of electrochemical energy reactions

The development of in situ spectroscopy methods has enabled detailed studies of the surface chemistry and structures of electrodes and/or electrocatalysts under active electrochemical conditions, providing real-time insights into reaction pathways at the electrode–electrolyte interface, which is mandatory for understanding electrochemical processes in energy devices. Key challenges in understanding the high electrochemical selectivity and activity of catalysts for energy reactions include measuring reaction kinetics, detecting changes in the chemical environment, identifying reaction intermediates, and linking material properties to device performance. This review examines the advanced utilities of various in situ and operando spectroscopic methods, such as Fourier transform infrared, Raman, X-ray absorption, and X-ray photoelectron spectroscopy, in the study of rechargeable lithium-ion batteries, supercapacitors, water-splitting (O₂ and H₂ evolution), and hybrid electrolysis with small molecule oxidation into hydrogen fuel and value-added chemical production. Emphasizing the significance of the various in situ/operando methods in optimizing catalyst design and improving energy storage and conversion efficiency and durability, we provide a systematic assessment of their roles in addressing major challenges in energy material research, summarizing their operational mechanisms, benefits, and limitations, and delivering guidance for future experimental strategies.

期刊介绍： Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications. The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms. Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC). Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
