The present invention relates to a process for the production of a zeolitic material having an MWW framework structure comprising YO.sub.2 and B.sub.2O.sub.3, wherein Y stands for a tetravalent element, said process comprising (i) preparing a mixture comprising one or more sources for YO.sub.2, one or more sources for B.sub.2O.sub.3, one or more organotemplates, and seed crystals, (ii) crystallizing the mixture obtained in (i) for obtaining a layered precursor of the MWW framework structure, (iii) calcining the layered precursor obtained in (ii) for obtaining the zeolitic material having an MWW framework structure, wherein the one or more organotemplates have the formula (I)

R.sup.1R.sup.2R.sup.3N   (I) wherein R.sup.1 is (C.sub.5-C.sub.8)cycloalkyl, and wherein R.sup.2 and R.sup.3 are independently from each other H or alkyl, and wherein the mixture prepared in (i) and crystallized in (ii) contains 35 wt.-% or less of H.sub.2O based on 100 wt.-% of YO.sub.2 contained in the mixture prepared in (i) and crystallized in (ii), as well as to a synthetic boron-containing zeolite which is obtainable and/or obtained according to the inventive process and to its use.

The present disclosure provides a metal-organic framework material/membrane composite material, a preparation method and a use thereof, which belongs to the technical field of water treatment. The method includes: mixing a membrane material with an alkali liquor, and performing a hydrolysis to obtain a hydrolyzed membrane; impregnating the hydrolyzed membrane in a metal salt aqueous solution and a framework organic solution in sequence, to form a metal-organic framework material/membrane composite material. In the composite material obtained by this method, the bonding strength between the membrane material and the metal-organic framework material is high, and it is not easy to separate them during the use and the composite material could be widely used. At the same time, the metal-organic framework material/membrane composite material obtained by this method has dual functionality, and thus could improve the efficiency of water treatment.
