Abstract: Provided is a process for the production of a zeolitic material having a BEA-type framework structure comprising YO2 and X2O3. The process comprises the steps of (1) preparing a mixture comprising one or more sources for YO2, one or more sources for X2O3, and seed crystals comprising one or more zeolitic materials having a BEA-type framework structure; (2) crystallizing the mixture; and (3) subjecting the zeolitic material having a BEA-type framework structure to an ion-exchange procedure with Cu and/or Fe. Y is a tetravalent element, and X is a trivalent element. The mixture does not contain an organotemplate as structure-directing agent, and the total amount of Cu and/or Fe in the ion-exchanged material ranges from 0.1 to 25 wt.-% calculated as Fe2O3 and CuO. Also provided is a zeolitic material having a BEA-type framework structure, and a method for the treatment of NOx by selective catalytic reduction (SCR).
