Abstract in English:

Nb substituted materials have shown remarkable activity in heterogeneous catalysis research for synthesis of fine chemicals. An extensive research had been carried out in presence of Nb compounds in catalysis as a promoters, active phase, support materials, solid acid catalysts or redox materials. Recently, Nb modified MCM-41 catalysts with different Si/Nb ratios have been synthesized and applied for gas phase Beckmann rearrangement of cyclohexanone oxime to caprolactam. In our investigations 100% cyclohexanone oxime conversion and >95% caprolactam selectivity were obtained.
