Heterogeneous Catalysis In heterogeneous catalysis, solids catalyze reactions of molecules in gas or solution. As solids – unless they are porous – are commonly impenetrable, catalytic reactions occur at the surface. To use the often expensive materials (e.g. platinum) in an eco-

heterogeneous nucleation is equal to the product of homogeneous nucleation and a function of the contact angle (θ): ... for θ=1800, f(θ) = 1 à no wetting of the surface, and thus no catalysis by the surface --- falling into the case of homogeneous nucleation. for θ= 00, f(θ) = 0 à full wetting, fully catalyzed ...
