Ultraviolet-Assisted Curing of Polycrystalline Pure-Silica Zeolites: Hydrophobization, Functionalization, and Cross-Linking of Grains

摘要

We have demonstrated that UV-assisted curing hydrophobizes spin-on Silicalite-1 films by means of silanol condensation and organic functionalization. The latter is uniquely achieved by the grafting of the organic template. Moreover, the silanol condensation enhances the fusion of the grains, minimizing the intergrain drawbacks. This has beneficial effects on the mechanical properties and pore size distribution. The success of the UV-assisted curing on spin-on Silicalite-1 films will inspire new avenues in modification of zeolite-like materials, supported or nonsupported.
