Homogeneous catalysis is a chemistry term which describes catalysis where the catalyst is in the same phase (ie. solid, liquid and gas) as the reactants. It is the opposite to heterogeneous catalysis.
Notice that two liquids can be different phases. Therefore, for example, the petrochemical alkylation process features heterogeneous catalysis, although both the catalyst (acid) and reactants (hydrocarbons) are liquids.
