Sol–Gel Synthesis and Characterization of Nanostructured TiO2/γ-Al2O3 Composite Membranes
Nanostructured TiO2/γ-Al2O3 composite membranes with various compositions were prepared by sol–gel method. The structural and textural properties of the composite membranes could be modified by the mixing ratio of boehmite sol and
titania sol, and calcination temperature. The existence of alumina in the composite membranes retarded anatase-to-rutile phase transformation, resulting in stabilization of textural properties. Defect-free composite membranes were confirmed by gas permeation test.
