An anion exchange membrane of layered silicalite nanosheets with surface quaternary ammonium cations

Abstract

Silicalite nanosheets (SNs) with surfaced quaternary ammonium cations of the template molecules are demonstrated as a new paradigm of building blocks for anion exchange membranes (AEMs). A multilayered SN membrane is fabricated on porous PVDF to achieve 3 A cm⁻² at 2.35 V and coulombic efficiency of 97% in alkaline water electrolysis.
