Photo-induced electrochemical reduction of water to hydrogen at ruthenium-modified polysulphur nitride electrodes
Abstract
Ruthenium redox couples have been immobilized on the perpendicular surface of poly sulphur nitride (SN)x, single-crystals which were used as electrodes and which, when maintained at about –0·10 V vs the saturated calomel electrode in H2SO4 solution and illuminated with visible light, evolve hydrogen gas continuously.
