The investigation of the type of active oxygen for the oxidation of propylene over bismuth molybdate catalysts using infrared and Raman spectroscopy showed that in the ..cap alpha..-phase (Bi/sub 2/Mo/sub 3/O/sub 12/) only a few types of lattice oxygens, possibly bridged oxide ions, were involved in the reaction; in the ..beta..-phase (Bi/sub 2/Mo/sub 2/O/sub 9/) most, but not all types of lattice oxygen were involved; and in the ..gamma..-phase (Bi/sub 2/MoO/sub 6/) all lattice oxygens were involved. The tests were conducted with oxygen-18 labeled oxygen.
