Hydrogen production from industrial byproducts – pv magazine International

US scientists have reported efficient plasmonic photocatalysis for the production of hydrogen from hydrogen sulfide, with no external heat source. Egypt, meanwhile, has started commissioning Africa’s first integrated green hydrogen plant. November 8, 2022 Sergio MatalucciRice University scientists have revealed a way to monetize byproducts in many industrial processes, by using plasmonic photocatalysis to facilitate the direct decomposition of hydrogen sulfide into hydrogen and sulfur. Hydrogen sulfide smells like rotten eggs, due to the breakdown of organic matter in the absence of oxygen, as in swamps and sewers. It is also found in many refinery streams. “Under visible light illumination and with no external heat source, up to a 20-fold reactivity enhancement compared to thermocatalysis can be observed,” wrote the team in “Direct H2S Decomposition by Plasmonic…
