In this chapter, we have briefly studied electrocatalysis. Electrocatalysis
plays an important role in many synthetic procedures, such as biodiesel production,
CO2
reduction, O2 evolution reaction, etc. Numerous electrocatalytic kinetic
characteristics are discussed to fairly assess the efficiency of electrocatalysts, including
overpotential (η), exchange current density (i0
) and Tafel slope (b). These variables are
essential and provide valuable insight into the electrochemical reaction's process. Due
to this, herein, we give a brief overview of these kinetic characteristics along with a
review of different electrocatalysts for various reactions.
Keywords: Biodiesel production, Current density, Electrocatalysis, Electrocatalytic kinetics, Overpotential, Tafel slope.
