“…A few studies have been reported earlier for the adsorption of hydrogen on palladium wires (Aldag and Schmidt, 1971) and films and supported Pd (Beeck, 1950;Schuit and van Rejjen, 1958) and also on Pdcarbon (Gentsch et al, 1972;Zakumbseva et al, 1977). However, no study on adsorption of the other reaction species (viz.…”

Adsorption isotherms for the single-component and multicomponent adsorption of o-nitrophenol hydrogenation reaction species (viz. o-nitrophenol, o-aminophenol, and water) from their methanol solution on Pd−carbon (4.6 wt % Pd) catalyst have been measured at the temperatures (278−308 K) at which the hydrogenation reaction is carried out. Both the single and binary adsorption data could be fitted well to Langmuir type adsorption equations. However, the Freundlich−Langmuir equation gives a better fit to the binary adsorption data. The adsorption of reaction species occurs in the order o-nitrophenol > o-aminophenol ≫ water and it is strongly influenced by the solvent used.
