Abstract: The disclosure generally provides zeolites having the CHA crystalline framework and methods of preparing the same. Provided herein are CHA zeolites containing intergrowths, a controlled framework aluminum distribution, or both. Further provided are CHA zeolites wherein crystals of the zeolite material have a predominantly flake-like morphology as determined by scanning electron microscopy (SEM). Further provided are catalyst compositions, articles, and systems including CHA zeolites promoted with a metal.

Abstract: The present disclosure provides catalyst compositions capable of reducing nitrogen oxide (NOx) emissions in engine exhaust. The catalyst compositions include metal ion-exchanged zeolites having a domain size of less than about 1500 Ångstroms (Å), a crystallographic strain of less than about 0.7%, or both. Further provided are catalyst articles coated with such compositions, processes for preparing such catalyst compositions and articles, an exhaust gas treatment system including such catalytic articles, and methods for reducing NOx in an exhaust gas stream using such catalytic articles and systems.

Abstract: The present disclosure provides methods of synthesizing a zeolite with a silica-to-alumina ratio (SAR) of 10 or greater comprising, e.g.: forming a reaction mixture including at least one alumina source, at least one silica source, and at least one organic structure directing agent, wherein the reaction mixture has a solids content of about 10% or greater, and crystallizing the reaction mixture at a temperature of 100° C. or less at atmospheric pressure to form a zeolite.

Abstract: The disclosure provides methods of preparing small pore zeolites, the method including using a first organic structure-directing agent and a second organic structure-directing agent to crystallize the zeolites, wherein the first organic structure-directing agent is bis-quaternary ammonium cations, and the second organic structure-directing agent is mono-quaternary ammonium cations. Further disclosed are small pore zeolites having a controlled framework aluminum distribution, and selective catalytic reduction catalyst compositions, articles, and systems including such zeolites promoted with a metal.
