Carbon–Al2O3–Ag composite molecular sieve membranes for gas separation
Phenolic resins loaded with two different inorganic fillers (boehmite (γ-AlO (OH)) and silver
(Ag)) were used to prepare composite carbon membranes. Polymer solutions containing γ-
AlO (OH) and AgNO3 were prepared and the effect of Ag on the transport properties of the
composite membrane was evaluated. The polymer solutions were coated on α-Al2O3 tubes
and carbonized in a single dipping-drying-pyrolysis step. After pyrolysis at 550° C, γ-AlO
(OH) yielded γ-Al2O3, and Ag agglomerated forming spherical nanoparticles of 30nm in …
