In this study, nanosized TPA-silicalite-1 was synthesized with a suitable molar composition of TPAOH: SiO2: H2O for thedevelopment of zeolite ceramic membranes to utilize as gas separation. As silica sources, TEOS, LUDOX AS-40 andCAB-O-SIL were used with the starting material of TPAOH. NaH2PO4, and a variety of acids and bases were used as promotersafter TPAOH, SiO2, H2O gel synthesis. To decrease synthesis time, a two step temperature change method was appliedto the synthesis of TPA-silicalite-1 at a low temperature. TPA-silicalite-1 synthesized was analyzed with XRD, SEM, BETand TGA. As a result, TPA-silicalite-1 powders with a particle size of 100 nm and a specific surface area of 416 m2/g wereobtained as optimum synthesis conditions when the two stage temperature change method was used with NaH2PO4 as promoter.
