摘要：动态现场原位(operando)表征是在接近过程工业反应条件下,揭示催化反应机理及工业催化剂结构演变的新兴动态结构解析技术。本文综述了operando表征技术在多相催化反应中的应用及发展趋势,从operando红外、operando拉曼、operando X射线衍射、operando穆斯堡尔谱、operando X射线吸收谱及operando X射线光电子能谱6个方面概述了operando技术的最新进展。此外,还介绍了正在兴起的operando联用技术,该技术综合多种operando技术为一体,能够在反应过程中对催化剂的结构全貌进行深度表征,实现工业催化剂的理性设计,将成为未来多相催化研究的重要手段。然而,目前operando技术的时间分辨率和空间分辨率仍需进一步提升,其巨大潜力依然有待开发。
Operando characterization is a cutting-edge technique for revealing the catalytic reaction mechanism and the dynamic structure evolution of industrial catalysts under the conditions close to industrial reaction.The development of operando technique and its application on heterogeneous catalysis have been reviewed,and the latest progress on operando infrared spectroscopy(IR),operando Raman,operando X-ray diffraction(XRD),operando M?ssbauer,operando X-ray adsorption spectra(XAS),and operando X-ray photoelectron spectroscopy(XPS)have been summarized.In addition,the coupling of various operando characterizations has also been introduced.Through this technique,the overall structure of the catalyst during reaction process can be characterized more deeply,and thus can realize the rational design of industrial catalysts.Therefore,we believe this coupling technique will become an important and prospective way to study heterogeneous catalysis.Nevertheless,the time and space resolution of current operando technique needs to be improved,and its enormous potential still requires to be further developed.
