At the atomic and molecular levels, accurately identifying the structural evolution of active sites, the evolution of reaction intermediates, and the mechanism of catalytic reactions play an important role for designing efficient catalysts in electrochemical energy storage and conversion technologies, though it remains highly challenging. This review systematically scrutinizes recent achievements in the dynamic investigation of solid-liquid electrochemical interfaces during electrocatalysis, using <em>in situ</em> synchrotron X-ray absorption fine structure (SR-XAFS) and synchrotron Fourier-transform infrared spectroscopy (SR-FTIR). It provides a comprehensive discussion on the continuous development of <em>in situ</em> SR-XAFS and SR-FTIR, with particular emphasis on the content of multi-scale monitoring the structural evolution of active centers. Moreover, the review highlights the unique and powerful role of correlative SR-XAFS/FTIR in exploring the dynamic of solid-liquid electrochemical interfaces in mainstream research areas such as electrocatalytic water splitting, oxygen reduction, nitrate reduction, and carbon dioxide reduction. Finally, the challenges and prospects of identifying the kinetic behavior of solid-liquid electrocatalytic interfaces in electrocatalytic materials under working conditions. This review aims to offer ample, reliable, and complementary information on the dynamic evolution of the interface during the electrocatalytic process, thereby guiding the rational design of advanced catalytic materials with outstanding activity, selectivity, and stability.</div></div>","PeriodicalId":100892,"journal":{"name":"Materials Today Catalysis","volume":"7 ","pages":"Article 100068"},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A thermal treatment under NH<sub>3</sub> (600 °C, 5 bar) was efficient and, interestingly, nitriding also occurred in a lower extent under N<sub>2</sub> (600 °C, 5 bar) for the sample containing ruthenium. The N-containing MXene produced ammonia under pure H<sub>2</sub> flow from temperatures lower than 250 °C.

However, the catalytic activity of MoS<sub>2</sub> is mostly confined to its edges while the basal plane remains inactive, limiting practical applicability. Fabrication of stable MoS<sub>2</sub> structures with enhanced active sites on a given surface area still remains a complex task. Here we introduce a substrate-agnostic, metal-organic chemical vapour deposition (MOCVD) method for large-area 3D dendritic nanostructures of 2D MoS<sub>2</sub>, termed as “MoS<sub>2</sub> nanowalls”. Using scanning and transmission electron microscopy (SEM/TEM), we elucidate the growth mechanism of the MoS<sub>2</sub> nanowalls and their branched dendritic structure. Even subjected to extreme pH environments (0 and 14) during the HER, the grown MoS<sub>2</sub> nanowalls show remarkable stability even after >170 hours of continuous operation and exhibit excellent catalytic activity with 10 mAcm<sup>−2</sup> current density achievable by applying low overpotentials (309±2 mV at pH = 0 and 272±2 mV at pH = 14).
