Abstract
We investigated the transformation of kaolin to ZSM-5 using hydrothermal synthesis method and the influence of organic template as a structure-directing agent. The formation of ZSM-5 from kaolin occurred via dissolution of kaolin to form amorphous silica. Zeolite-like analcime produced when the hydrothermal treatment was extended to 18 h. We found synergistic effect of using a mixture of TPAOH and TPABr organic template to enhance kaolin dissolution, initiate ZSM-5 formation and inhibit the transformation of ZSM-5 to analcime. The ZSM-5 framework formed after crystallization for 6 h by using the mixture of TPAOH and TPABr, while when using TPAOH or TPABr only, ZSM-5 formed at longer crystallization time, i.e. 12 h.
