Recent social, industrial, and technological advancements have heightened the demand for energy, primarily met by fossil fuels, leading to the depletion of energy resources and environmental problems. The quest for sustainable alternative energy has increased interest in electrocatalysis, a promising strategy that links electrochemistry to catalysis. This approach promotes green and sustainable energy and chemistry technologies by facilitating the conversion of common molecules such as water, carbon dioxide and nitrogen into high-value chemical products such as hydrogen, hydrocarbons, oxygenates, ammonia and carbonates. In this chapter, the authors summarized electrocatalyst, electrocatalysis and the basics of electrocatalysis. Then, they briefed various electrocatalysis applications and external fields-enhanced electrocatalysis to the readers.
