Modern multiphase catalysis: new developments in the separation of homogeneous catalysts.

Homogeneous catalysts are powerful tools for the synthesis of fine chemicals, pharmaceuticals and materials, however their exploitation on an industrial scale is often held back due to the challenges of separating and recycling the catalyst. This perspective focuses on approaches to multiphase catalysis that have emerged in the last decade, highlighting methods that can address the separation issues and in some cases result in superior catalyst performance and environmental benefits.
