Abstract

Abstract: Cellulose–poly(ferrocenylsilane) (PFS) polyionic liquid (PIL) composite sponges are fabricated by codissolution of cellulose and PFS‐PIL, followed by solvent exchange and freeze‐drying. The hybrid sponges are used to in situ produce and immobilize palladium nanoparticles (Pd NPs), leading to Pd NP‐decorated porous supports. The formation of Pd NPs is confirmed by TEM and XPS measurements. The as‐prepared cellulose/PFS‐PIL@Pd sponges exhibit a high catalytic activity in the reduction of 4‐nitrophenol (4‐NiP) to 4‐aminophenol (4‐AmP). As a variety of metal NPs may be immobilized using this method, these sponges constitute a promising new class of catalytic porous supports. Abstract : A symbiotic sponge with natural and synthetic polymers is synthesized by codissolution of cellulose and a poly(ferrocenylsilane) polyionic liquid. Palladium (Pd) nanoparticles are synthesized in situ and immobilized in the composite sponge without an external reducing agent. The as‐prepared Pd nanoparticle loaded sponge exhibits excellent performance in the reduction of 4‐nitrophenol to 4‐aminophenol.
