Electrochemical Flow Cell for in-situ/Operando Analysis
In-situ/Operando analysis is an analytical methodology wherein the spectroscopic characterization of materials undergoing reaction is coupled simultaneously with measurement of catalytic activity and selectivity. The primary concern of this methodology is to establish structure-reactivity/selectivity relationships of catalysts and thereby yield information about mechanisms. Other uses include those in engineering improvements to existing catalytic materials and processes and in developing new ones. In situ/operando analysis requires measurement of the catalyst under (ideally) real working conditions, involving comparable temperature and pressure environments to those of industrially catalyzed reactions. In our lab, various In situ/operando analysis was prepared for mechanism and characterize study using techniques such as XRD, ICP, XAFS, and Raman.
