Pd immobilized on magnetic chitosan as a heterogeneous catalyst for acetalization and hydrogenation reactions

- The CS-Fe3O4-Pd composed of magnetic chitosan materials and Pd nanoparticles.
- The CS-Fe3O4-Pd was found to be an efficient catalyst for hydrogenation and acetalization.
- The catalyst was easily recovered by an external magnet from the reaction mixture.
- The catalyst can be recycled five times without any significant loss in activity.
