Recently, Professor Huagui Yang's team from East China University of Science and Technology, in collaboration with Professor Zheng Jiang's team from the University of Science and Technology of China, authored a review paper introducing the cross-scale application of in situ/operando synchrotron radiation analysis technology in CO2/CO reduction reactions. The relevant article was published in "Angewandte Chemie International Edition."
The review summarizes and introduces the cross-scale application of synchrotron radiation in CO(2)RR, ranging from atomic to mesoscopic scales. It covers dynamic evolutions from electronic structures, atomic arrangements, molecular configurations, crystal structures to device applications, providing a comprehensive analysis of the complex dynamic processes of CO(2)RR. Considering that the performance and stability of CO(2)RR electrolysis highly depend on the electrolysis device, the paper not only discusses the characterization of catalyst structures but also elucidates the application potential of synchrotron radiation technology in revealing dynamic changes inside the electrolysis cell and accelerating the development of industrial devices.

Furthermore, the author envisions utilizing fourth-generation advanced light sources to decode the dynamic evolution process from materials to devices. This includes enhancing the sensitivity of synchrotron characterization techniques in surface analysis, improving spectral energy resolution and spatiotemporal resolution, designing devices suitable for in situ characterization, and developing characterization techniques tailored to device scales. The development of multiple characterization techniques synchronized in joint application platforms is also envisaged. Thanks to the flourishing development of fourth-generation synchrotron facilities, advanced light sources will greatly enrich the applications of synchrotron accelerators, opening up new perspectives for CO(2)RR and other important catalytic reactions.
