Heterogeneous catalysis involves systems in which the reaction takes place in different phases 9 The word "phase" here refers to solid, liquid, gas, or immiscible liquids like oil and water Generally the catalyst is in the solid phase, and the reactants are gases or liquidsIn catalysis Heterogeneous catalysis Many catalytic processes are known in which the catalyst and the reactants are not present in the same phase—that is, state of matter These are known as heterogeneous catalytic reactionsDefinition of Heterogeneouscatalysis In chemistry, heterogeneous catalysis refers to the form of catalysis where the phase of the catalyst differs from that of the reactants Phase here refers not only to solid, liquid, vs gas, but also immiscible liquids, eg oil and water
