An updated review and perspective on efficient hydrogen generation via solar thermal water splitting

WIREs Energy and Environment, Volume 13, Issue 4, July/August 2024.
Solar thermal water splitting (STWS) produces renewable (or green) hydrogen from water using concentrated sunlight. Abstract Solar thermal water splitting (STWS) produces renewable (or green) hydrogen from water using concentrated sunlight. Because STWS utilizes energy from the entire solar spectrum to drive the reduction–oxidation (redox) reactions ...
