Abstract

The competitive adsorption of catalyst poisons and adsorbed H is of interest in relation to their effects in promoting H absorption into transition metals. The capacity of three sulfur- containing compounds, thiourea,-cysteine and 2, 2′-diethanolsulfide (DES), to block H adsorption at Pt electrodes in both the under
