On the Nature of the ‘Heterogeneous' Catalyst: Nickel-on-Charcoal
The Journal of Organic Chemistry, 2002Results from aromatic aminations and Kumada couplings, together with spectroscopic analyses (TEM, EDX, ICP-AES, React-IR), reveal that catalysis using nickel-on-charcoal (Ni/C) is most likely of a homogeneous rather than heterogeneous nature. In the course of a reaction with Ni/C, nickel bleed from the support was calculated to be as high as 78 ...

“HETEROGENIZING” HOMOGENEOUS CATALYSTS
Catalysis Reviews, 1974Abstract For many years, it has been customary to classify catalysts as “homogeneous” or “heterogeneous.” The former commonly operate through the formation of “intermediate compounds,” and the latter, by adsorption of the reactants on the catalyst surface.

Introduction to Heterogeneous Catalysts
1992Abstract An aspect of inorganic solids that has frequently been neglected by solid state chemists is the catalytic property. The reason for this neglect can be primarily attributed to the great difficulty of achieving a detailed understanding of surface structure and reactivity.
