The o-p interconversion of H₂ over Fe-synthetic-NH₃ catalyst was studied as a function of the temperature, pressure, time of contact, and presence of various poisons. Both types of activated adsorption of H₂ on Fe are poisons for the conversion of o-p-H₂ at liquid-air temperature. The low-temperature of o-p conversion over Ni and Pt is also inhibited by the activated adsorption of H₂.
