(461d) Guiding the Synthesis Routes to Prepare Small Pore Zeolites for Environmental and Industrial Applications

Small pore zeolites containing large cavities in their structure have become important catalysts for industrial processes (i.e. for the methanol-to-olefins, MTO) and environmental applications (i.e. emission control of harmful gases, particularly nitrogen oxides, NOx). The ability to design different framework topologies (particularly presenting intergrowth crystalline phases) and to control their chemical composition have a tremendous impact in the catalytic performance and/or stability of these small pore zeolites.

Different strategies will be presented for improvement of the efficiency in the preparation of some of the industrially-relevant small-pore zeolite catalysts (i.e. costs), their catalytic performance, and/or their resistance against catalyst deactivation, by rationalizing the use of different inorganic and organic structure directing agents (OSDA). The synthesized materials have been evaluated as catalysts for the selective catalytic reduction (SCR) of NOx and methanol-to-olefins (MTO).
