Abstract

Microfibrous-structured SS-fiber@beta composites are synthesized by coupling dip-coating method with a seed-assisted dry-gel conversion method. The beta crystals in zeolite shell are formed by growth on the surface of pre-added beta seeds and TEAOH-induced nucleus. One interesting point is that this approach is working highly effectively and efficiently even at high dry gel SiO₂/Al₂O₃ ratio of 200 (corresponding to 207 in the beta zeolite shell). Such SS-fiber@beta composites show great potentials for the heat/mass transfer limited reactions due to their hierarchical porosity, small crystals, controllable acidity as well as our distinctive microfibrous-structured design.
