ESR study of electron transfer to oxygen adsorbed on supported catalysts containing molybdenum and vanadium

Paramagnetic species which appeared upon low-temperature adsorption of oxygen on the surface of partially reduced Mo MgO , V MgO , Mo Al 2 O 3 , and V Al 2O 3 catalysts were studied. The results show that on chemisorption a transfer of electron from the supported atoms to molecules O 2 take place an...

Description
Summary:Paramagnetic species which appeared upon low-temperature adsorption of oxygen on the surface of partially reduced Mo MgO , V MgO , Mo Al 2 O 3 , and V Al 2O 3 catalysts were studied. The results show that on chemisorption a transfer of electron from the supported atoms to molecules O 2 take place and that the appearing O 2 − species are stabilized on the ions of host lattices or on supported ions depending upon the temperature of the experiments.
