Synthesis of Silicalite-1 Membranes on the Surface of Stainless Steel
Silicalite-1 (pure silica MFI) membranes were hydrothermally synthesized on pretreated surface of two common stainless steel materials, i.e., AISI 304 and 316L. XRD and SEM techniques were used to characterize the membranes. Various membrane morphologies can be obtained by adjusting synthesis conditions such as the H2O/SiO2 ratio in the start colloid, the crystallization time and temperature as well as the substrate materials. The silicalite-1 membranes on the stainless steel surface show potential applications for regenerative fuel cooling technology in high speed flight field.
