Abstract
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.
