Perovskite in catalysis and electrocatalysis

Catalytic or electrochemical water splitting is a promising approach for hydrogen production to address the energy crisis and has been extensively explored over the past several decades. However, the success of this method depends on the efficiency of the photocatalytic materials or systems enough to meet the commercial interest. Although several semiconductor nanoparticles show promising potential, the choices are limited owing to the stability, appropriate band gap and affordability. Alternatively, doped and undoped perovskite structures are recently gaining interest to be explored in the fields of catalysis and electrocatalysis due to their tunable electronic structure and unique physico-chemical properties. Perovskites offer a wide range of possibilities owing to their flexibility in composition, structure, and shape. This book chapter includes an introduction to the field of water splitting and the unique structural properties of the perovskites, followed by the state-of-the-art research activities regarding the application of perovskite in catalysis and electrocatalysis and the related mechanism and kinetics of the catalytic reactions.
