Homogeneous catalysts have high activities and selectivities but are not recycled.  Heterogeneous catalysts often have lower activity or selectivity but can be reused.  Exploiting advanced separation techniques involving tunable solvents and gas-expanded liquids, homogeneous catalysts may be used in reaction followed by a heterogeneous separation of the catalyst for recycle.
