Abstract

High-silica zeolite Y (SiO2/Al2O3 = 20.4) was synthesized in high yield (ca. 60%) via a top-down strategy using TBAOH and TMAOH as organic structure-directing agents, yielding nanocrystals (50-100 nm) with ultralow Na content (Na/Al = 0.02) and homogenous framework Al distribution that demonstrated enhanced catatytic performance for dimethoxymethane carbonylation.
