Abstract: A catalyst for the selective catalytic reduction of NOx comprises a zeolitic material which comprises (A) one or more zeolites having a GME framework structure containing YO2 and X2O3, and optionally further comprises one or more zeolites having a CHA framework structure containing YO2 and X2O3, and/or comprises, (B) one or more zeolite intergrowth phases of one or more zeolites having a GME framework structure containing YO2 and X2O3 and one or more zeolites having a CHA framework structure containing YO2 and X2O3, wherein Y is a tetravalent element, and X is a trivalent element, and the zeolitic material contains Cu and/or Fe as non-framework elements in an amount ranging from 0.1 to 15 wt. % calculated as the element and based on 100 wt. % of YO contained in the zeolitic material. Also provided are a process for its preparation, and a use in a method for the selective catalytic reduction of NOx.

Abstract: The present invention relates to a process for the preparation of a catalyst for selective catalytic reduction comprising• (i) preparing a mixture comprising a metal-organic framework material comprising an ion of a metal or metalloid selected from groups 2-5, groups 7-9, and groups 11-14 of the Periodic Table of the Elements, and at least one at least monodentate organic compound, a zeolitic material containing a metal as a non-framework element, optionally a solvent system, and optionally a pasting agent,• (ii) calcining of the mixture obtained in (i); and further relates to a catalyst per se comprising a composite material containing an amorphous mesoporous metal and/or metalloid oxide and a zeolitic material, wherein the zeolitic material contains a metal as non-framework element, as well as to the use of said catalyst.

Abstract: The present invention relates to a process for the preparation of a zeolitic material having a CHA-type framework structure comprising YO2 and X2O3, wherein said process comprises the steps of: (1) providing a mixture comprising one or more sources for YO2, one or more sources for X2O3, one or more optionally substituted ethyltrimethylammonium cation-containing compounds, and one or more tetraalkylammonium cation R1R2R3R4N+-containing compounds as structure directing agent; (2) crystallizing the mixture obtained in step (1) for obtaining a zeolitic material having a CHA-type framework structure; wherein Y is a tetravalent element and X is a trivalent element, wherein R1, R2, and R3 independently from one another stand for alkyl, wherein R4 stands for cycloalkyl, and wherein the YO2:X2O3 molar ratio of the mixture in (1) ranges from 2 to 1,000, as well as to zeolitic materials which may be obtained according to the inventive process and to their use.
