Methylcyclohexane dehydrogenation on Rh/γ‐Al₂O₃ catalysts

Abstract

Abstract The influence of the Rh loading on the surface properties and catalytic behaviour of Rh/γ‐Al 2 O 3 catalysts has been studied. The series of catalysts presents differences in metal dispersion, reducibility, surface composition and catalytic activity. All the data reported suggest that the differences in catalytic behaviour in the methylcyclohexane dehydrogenation reaction can be explained in terms of electron‐deficient rhodium clusters, essentially when the metal particle size becomes smaller than 15 Å.
