Hierarchically porous Sn-β zeolites via an OSDA-free synthesis

Abstract

Hierarchically porous Sn-β zeolites were synthesized for the first time via a low-cost and environmentally benign strategy without using an organic structure directing agent, which still showed higher catalytic performance for triose sugar (DHA) into lactate than the traditional nano-sized Sn-β zeolites synthesized with expensive tetraethylammonium hydroxide.
