Abstract: The present invention relates to a catalyst for hydrogen peroxide activation, wherein the catalyst comprises Ti, Si, and O, wherein the catalyst displays a water adsorption (W), a concentration (C) of bridging μ2 η2-peroxo species per Ti in the H2O2-activated catalyst as determined by quantitative 17O NMR spectroscopy, and a specific activation factor (A) according to formula I, wherein in accordance with formula I, the activation factor is the multiplication product of the water adsorption and the concentration of bridging μ2 η2-peroxo species per Ti in the H2O2-activated catalyst: A=W×C (I). The present invention further relates to a method for the preparation of a catalyst molding as well as to a catalyst molding comprising a catalyst for hydrogen peroxide activation obtainable or obtained by said process. Yet further, the present invention relates to a process for the activation of hydrogen peroxide, and to the use of the inventive catalyst or of the inventive catalyst molding in a reaction involving C—C bond formation and/or conversion.

Abstract: Described herein is a process for producing a zeolitic material having an MWW framework structure containing YO2 and B2O3, in which Y stands for a tetravalent element. The process includes the steps of (i) preparing a mixture containing one or more sources for YO2, one or more sources for B2O3, one or more organotemplates, and seed crystals, (ii) crystallizing the mixture obtained in (i) for obtaining a layered precursor of the MWW framework structure, and (iii) calcining the layered precursor obtained in (ii) for obtaining the zeolitic material having an MWW framework structure. Also disclosed herein are synthetic boron-containing zeolites obtain by the process and uses thereof.
