摘要

Zeolite W nanorods (MER topology) containing K cation (K-W) has been synthesized for the first time without the use of organic structure-directing-agent (OSDA). With microwave heating, the synthesis time can be shortened to 12 min, which is much shorter than the time required by conventional method (10 days, 150 degrees C). The study reveals that the use of basic synthesis condition and K+ as the cation source are essential in order to produce zeolite W nanocrystals. The K-W displays bundle-like nanorods morphology with highly accessible hierarchical mesoporosity. The nanocrystals are colloidal stable in water and contain large amount of extraframework K+ cations. The K-W has demonstrated very good performance as a recyclable base catalyst in Henry (nitroaldol) reaction of vanillin with nitroethane (conversion 86.5%).
