Arsenic and platinum deposition during cathodic hydrogenation

Journal Article · · Scr. Metall.; (United States)

These experiments show that arsenic promoter and supposedly inert platinum anode material are co-deposited with hydrogen on the cathode surface during cathodic hydrogenation. The arsenic is initially deposited faster than the platinum, thus accelerating the deposition of platinum. Hydrogen (deuterium) uptake by the cathode appears to increase to a high saturation level as the amount of metal deposited reaches the equivalent of a monolayer or more of surface coverage. The presence of these deposits should be considered in hydrogen embrittlement tests made under dynamic cathodic electrolysis. 3 figures, 1 table.
