Ordered 3D Hexagonal Mesoporous Silica Membranes: Synthesis and Characterization

  • Michaela Klotz (a1), Sophie Besson (a1), Christian Ricolleau (a2), Florence Bosc (a3) and André Ayral (a3)...


A ceramic membrane with an ordered mesoporous top layer has been developed. The active layer possesses a close-packed hexagonal network of spherical pores. Results on permeation of helium and argon through the membrane are presented and correlated with the structural and textural properties of the top layer. New insights are given on the porosity of this close-packed hexagonal structure.
