Abstract

H/D isotope separation faces critical challenges in terms of separation efficiency and cost. This study presents a novel, scalable fabrication of centimeter-scale, defect-free vermiculite monolayer membranes via a modified Langmuir–Blodgett method. These membranes demonstrate H/D separation efficiency comparable to monolayer graphene, promising cost-effective applications.
