Cu/Fe 3 O 4 embedded polyethersulfone beads: a scalable and magnetically separable catalyst for hydrogen evolution from ammonia borane and selective hydrogenation of cinnamaldehyde

In this work, we developed magnetically separable Cu@Fe 3 O 4 :PES based catalyst beads that enable both efficient hydrogen generation from ammonia borane (AB) and tandem reduction of organic compounds under mild and environmentally benign conditions.
