Preparation and application of cobalt-based compounds

Abstract Hydrogen is considered a promising renewable energy source due to its abundance, releases high heat, clean, and renewable. Water splitting is used as a strategy engineering for hydrogen production. The development of efficient electrocatalysts to reduce the overpotential of water splitting is the key to improving energy efficiency and hydrogen production rate. This study focuses on the reaction mechanism of water splitting, sticks to the essential structure-activity relationship, and emphasizes the design and optimization of electrocatalytic performance at the atomic scale. The related surface modification methods such as vacancy, doping, and interface are used to improve the performance of the electrocatalyst[1].
