Abstract
The nature of the reversible adsorption of hydrogen on nickel, the determination of which was reported for the first time in a preceding paper, has been investigated in terms of heat of adsorption and by the effect of catalyst reduction and the effect of water vapor as a carrier gas impurity. The heat of adsorption was found to be about 2 kcal/mole at low temperature (−195–−100 °C) and about 13 kcal/mole at around 0 °C (−30–60 °C), which indicates two different types of adsorption. The adsorption sites for them appeared to be developed in the early stage of reduction. Adsorbed water is likely to activate another type of hydrogen adsorption.
