How to extract kinetic information from Tafel analysis in electrocatalysis

Abstract

Electrocatalysis has become increasingly attractive in aiding transformation to green chemical industries. Proper evaluation and in-depth understanding of electrocatalysts are critical to designing high-performance electrocatalysis systems. Tafel analysis is thus of great importance as it allows reliable performance comparison among different reports and provides insight into the reaction mechanism. This Tutorial discusses the Tafel analysis from experimental and theoretical perspectives. The principle of the Tafel analysis is revisited, and the procedure of mechanism investigation based on the Tafel analysis is included.
