Accelerated Crystallization of Zeolites via Solid Boron Free Radicals.

ABSTRACT: The highly efficient synthesis of titanium silicate-1 (TS-1) zeolite remains a challenge. In this work, solid boron free radicals within hexagonal boron nitride (h-BN) were employed to accelerate the crystallization of TS-1. With the introduction of h-BN (1-10 wt % of SiO₂) into the traditional hydrothermal synthesis system, TS-1 zeolite can be obtained within 6-24 h with yields of 90-96%. The geometric matching between h-BN layered structure and the TS-1 crystal plane was observed by both TEM analysis and theoretical modeling, while solid-state free radicals generated at the edges of h-BN with defects were evidenced by aberration-corrected transmission electron microscopy and EPR analysis.
