Hydrogen has a lot of promise as an alternative to various carbon containing fuels as burning it releases only water which does not contribute to climate change. However, the standard method of producing hydrogen uses methane as the source, releases carbon dioxide and requires high temperatures and pressures meaning it cannot be considered a sustainable process. Photocatalysis, electrocatalysis and the combining of the two in photoelectrocatalysis offer pathways to producing hydrogen from different starting materials and with lower energy costs, which will be essential to making sustainable hydrogen fuel a reality. Advances in Photocatalysis, Electrocatalysis and Photoelectrocatalysis for Hydrogen Production brings together the latest developments in applying these types of catalysis to producing hydrogen. This book is an important resource for anyone working in photo- and electrocatalysis or with an interest in routes for green hydrogen.
