Ultrathin membranes of single-layered MoS2 nanosheets for high-permeance hydrogen separation

Single-layered MoS₂-based ultrathin membranes with well-controlled thicknesses are prepared by a simple filtration method, and for the first time applied to gas separation. These membranes exhibit superior H₂/CO₂ separation performance and extremely high H₂ permeance. The H₂/CO₂ separation performance surpasses the state-of-the-art upper-bound of polymeric and inorganic membranes.Single-layered MoS₂-based ultrathin membranes with well-controlled thicknesses are prepared by a simple filtration method, and for the first time applied to gas separation.
