Mesopore formation in zeolite H-SSZ-13 by desilication with NaOH

Autor: Sommer, L., Mores, D., Svelle, S., Stöcker, M, Weckhuysen, B.M., Olsbye, U.

A zeolite H-SSZ-13 material with CHA topology and a Si/Al ratio of 14 was treated with sodium hydroxide solutions of various concentrations. The post synthesis treatment led to desilication of the framework accompanied by mesopore formation. N2-physi

Chemical Imaging of Catalyst Deactivation during the Conversion of Renewables at the Single Particle Level: Etherification of Biomass-Based Polyols with Alkenes over H-Beta Zeolites

Autor: Parvulescu, A.N., Mores, D., Stavitski, I., Teodorescu, C.M., Bruijnincx, P.C.A., Klein Gebbink, R.J.M., Weckhuysen, B.M.

The etherification of biomass-based alcohols with various linear alpha-olefins under solvent-free conditions was followed in a space- and time-resolved manner on 9 mu m large H-Beta zeolite crystals by confocal fluorescence microscopy. This allowed u
