A small magnet is used to separate magnetic nanoparticle catalysts containing base sites from polymeric resin beads containing acid sites. The normally incompatible catalysts can be used simultaneously in the same vessel by sequestering each catalyst in a separate solid.

Using the unique properties of new nanometer-scale magnetic particles, researchers have for the first time separated for reuse two different catalysts from a multi-step chemical reaction done in a single vessel.
