Morphology and activity of vanadium-containing catalysts for the selective oxidation of benzene to maleic anhydride

摘要

The morphology and activity of vanadium catalysts are studied using a number of physicochemical methods: electron microscopy, electron paramagnetic resonance, and infrared spectroscopy. It is found that the active agent of the conversion of benzene to maleic anhydride over modified vanadium catalysts is the V ~(4+) ion in the vanadyl configuration.
