Abstract
The influence of the Rh loading on the surface properties and catalyti c behaviour of Rh/gamma-Al2O3 catalysts has been studied. The series o f catalysts presents differences in metal dispersion, reducibility, su rface composition and catalytic activity. All the data reported sugges t that the differences in catalytic behaviour in the methylcyclohexane dehydrogenation reaction can be explained in terms of electron-defici ent rhodium clusters, essentially when the metal particle size becomes smaller than 15 angstrom.
