Membranes only: A hybrid organic–inorganic membrane for CO 2 separation is prepared by sol–gel deposition of a microporous ethylene‐bridged silsesquioxane layer onto a multilayer support. Low CO 2 permeance is imparted by doping acidic niobium centers into the hybrid silica network. The membrane exhibits superior hydrothermal stability with He/CO 2 selectivities as high as 3700.
