Homogeneous and Heterogeneous Catalysis
... In general, heterogeneous catalysis requires the diffusion of one or more reactants to the catalyst surface, followed by the absorption onto a solid catalyst. The use of heterogeneous catalysts has both advantages and disadvantages. On one hand, diffusion to a binding site on a solid catalyst can of ...
