Characterization of alumoxane-derived ceramic membranes

摘要

Atomic force microcopy, nitrogen adsorption-desorption, and measruements of intrinsic permeability are used to characterize ceramic membranes made using a newly developed alumoxane-based method conceived as an environmentally benign process. AFM, BET and permeability data indicate that the alumoxane synthesis pathway can be used to readily produce unsuported membranes with pore sizes in the range of 10-20 nm and with permeabilites comparable to those of anodized alumina membranes.
