Materials for Hydrogen Production

Abstract

Achieving global decarbonization goals by 2050 hinges on green hydrogen production via water electrolysis. With increasing demand for hydrogen in renewable energy, industrial sectors, and transportation, the importance of this technology continues to grow. This chapter delves into hydrogen production fundamentals and recent advancements in water electrolysis, emphasizing its pivotal role in generating green hydrogen. Key mechanisms of water splitting, such as electrocatalysis, photocatalysis, and photoelectrolysis, are explored. Special focus is given to advanced electrocatalysts, including both noble metals and cost-effective alternatives, that enhance the hydrogen evolution and oxygen evolution reactions. Innovative photocatalytic materials, including transition metal chalcogenides and phosphides, are highlighted for their efficiency gains through heteroatom doping and cocatalyst integration. Storage solutions and hydrogen's industrial applications in sectors like energy, chemicals, and transportation are also examined, presenting a roadmap for future development.
