Keywords: Plasma

In “contact glow discharge,” an electrolytic reaction where plasma and water come into contact, phenomena where the Faraday efficiency exceeds 1 have been reported, but the reaction mechanism remains unclear. We aim to develop a plasma-driven electrolysis method that generates stable direct-current plasma in water, elucidate the mechanism behind the phenomenon where hydrogen production increases significantly compared to conventional electrolysis, and establish a highly efficient hydrogen production technology.
