Реферат:
The complexes present in the active form of vanadium catalysts for SO2 oxidation have been studied with use of 51V, 17O, and 23Na NMR at room temperature and at 500 °C in reaction mixture media. In the V2O5K2S2O7 melt the coordination of vanadium(V) with 2 or 3 pyrosulfate anions takes place. At vanadium concentrations above 1.5 mol/liter associated complexes are formed. These species are most active in the oxidation of SO2. This conclusion follows from measurements of the catalytic activity of V2O5K2S2O7 supported on Pyrex tubes. 51V NMR shows that the interaction of vanadium with SO2 results in the formation of tetracoordinated surface complexes. These tetracoordinated vanadium complexes which are Catalytically inactive form active species upon interaction with monomeric vanadium-pyrosulfate complexes in the melt.
