Characterization of electrocatalyst

Abstract

In the process of developing a catalyst, understanding their structure and properties is considered essential as it is obligatory to improve their performance or to resolve a failure issue. Hence, the purpose of this invited chapter is to give a brief summary of various characterization tools specifically, X-ray Diffraction (XRD), Brunauer, Emmett, and Teller (BET) technique, Infrared Spectroscopy (IR), UVvisible spectroscopy, Electron microscopy, and Electrochemical techniques, where we discussed the principle, application, and challenges associated with the catalyst characterization. Also, in this chapter, we illustrated the analysis and interpretation of characterization data with an example for better understanding. These perceptive investigations of different characterization tools lead to the establishment of empirical relationships between various factors that govern catalytic activity.
