Abstract Scope |
Many works reported the effect of poisonous gases such as CO, CO2, CH4, and H2S on the hydrogen transport process across a palladium membrane. A lot of attempts were made including palladium alloys to remedy these problems but still, most of them remain a bottleneck. The hydrogen processes on the membrane surface are the key players in the whole transport lane. However, we try another alternative which is doping the palladium surface with another catalytic metal specifically platinum. The hydrogen adsorption and dissociation on the palladium-doped surface and the effect posed by CO and H2S were studied. Our findings claimed that hydrogen adsorption is highly enhanced as dissociative adsorption with minimized energy. The palladium
platinum membrane surface maintains the same CO effect as that on bare palladium and minimizes the effect of H2S. |
