摘要

Catalysis, which is central to the energy and chemical industries, constitutes a dynamic process that involves multiple stages, ranging from activation and deactivation to rapid catalytic cycles. Comprehending these dynamic processes is crucial for optimizing catalytic reactions and developing innovative catalytic systems. This review centers on the integration of operando spectroscopies with transient analysis to acquire quantitative dynamic information directly from spectroscopic investigations of catalytic processes. Operando spectroscopies facilitate real-time observations of dynamic changes occurring during catalysis, while transient experiments yield insights that extend beyond steady-state kinetics by examining catalysts’ responses to and recovery from dynamic conditions. This review aims to underscore the significance of integrating multiple spectroscopic techniques and transient methodologies to yield quantitative insights into catalytic processes, elucidating in real time the relationships between active structures, surface intermediates, and catalytic kinetics.
