1. Molecular sieve macrostructures prepared by resin templating
Sammanfattning : A novel template-based method for the preparation of molecular sieve macrostructures was developed. Silicalite-1, ZSM-5 and zeolite beta spheres were prepared by the method. The procedure was also used to produce amorphous silica macrostructures. Anion exchange resin beads were employed as macrotemplates to host the guest silica materials. LÄS MER
2. Zeolite macrostructures
Sammanfattning : The preparation of zeolite macrostructures in the form of bilayered hollow tubes and microspheres is presented. The bilayered hollow ZSM-5/silicalite-1 tubes were prepared using carbon fibers as a substrate. The surface of the fibers was modified and colloidal silicalite-1 seed crystals adsorbed. LÄS MER
