Synthesis and characterisation of microporous titania membranes by dip-coating of anodised alumina substrates using sol–gel method

“…Sekulic et al have studied nanoporous membranes of amorphous silica with pore sizes under nanometer [9]. Several works have been carried out for the synthesis of microporous and nanoporous titania and alumina membranes on different mesoporous substrates [10][11][12][13]. The process is often consisted of multiple coating operations of intermediate and top layers on a particulate asymmetric mesoporous substrate [10].…”

“…The process is often consisted of multiple coating operations of intermediate and top layers on a particulate asymmetric mesoporous substrate [10]. A direct synthesis method of titania membranes has been also introduced using a special arrangement which allows the reaction of the reactants directly in the pores of a tubular alumina support or on its surface, respectively [11]. By this direct synthesis, the number of technological steps can be reduced which is the main advantage of the method.…”

Spontaneous and Self-Assembled Line Formations on Silicon Substrates with Vanadium Pentoxide Sol−Gels

“…Sol−gel chemistry often involves the use of Al or Si. The versatility of these materials allows them to be used for ceramic membranes, coatings, , films, and numerous other applications. With so much focus on the Al and Si based sol−gels, vanadium sol−gels have not been studied as extensively.…”
