Abstract
Heats of adsorption, heat capacities and isotherms have been measured for CO adsorbed on exfoliated graphite (Grafoil) over a wide range of temperature and for surface coverages up to 1·2 monolayers. Both integral and differential properties have been obtained and are subjected to relatively simple analysis. From a comparison of the results with similar ones for N2 adsorption, some conclusions can be drawn about the phase diagram for adsorbed CO and about the character of the adsorption. The relative behaviour of the two gases is explicable in terms of dispersion interactions. Simulation calculations of the integral heat of adsorption of CO are made as a function of surface coverage.Keywords
