### Heterogeneous vs Homogeneous

Can someone describe the difference between a heterogeneous and homogeneous catalyst?

### Re: Heterogeneous vs Homogeneous

A homogeneous catalyst is a catalyst that is the same phase as the reactants. For example, if the reactants in a reaction are composed of gases and the catalyst is also a gas, then the catalyst is classified as a homogeneous catalyst.

A heterogeneous catalyst is a catalyst that is present in a different phase from that of the reactants.
