CytroCell@PIL: A New Citrus Nanocellulose‐Polymeric Ionic Liquid Composite for Enhanced Anion Exchange Membranes

Year: 2025

Type: article

Abstract: ABSTRACT Enhancement of alkaline water electrolysis requires the development of anion exchange membranes (AEMs) combining high permselectivity with a low resistance to ion transport and stability during prolonged contact with a concentrated alkaline solution. We now report that CytroCell@PIL, a mixed matrix membrane obtained by a synergic combination of CytroCell micronized citrus cellulose mixed at a 1 wt% load with a polymerizable ionic liquid (triethyl(4‐vinylbenzyl)phosphonium tetrafluoroborate), shows vastly enhanced chemical and physical stability along with promising ionic conductivity. These findings establish the proof of concept toward the development of technical and economically viable large‐area AEMs using polymeric membranes chemically and physically stabilized by CytroCell sustainably sourced via cavitation of industrial citrus processing waste conducted in water only.
