A scanning electron microscope and microprobe analyzer have been used to examine the surfaces of vanadium-molybdenum catalysts on aerosil. It is found that the phase VMo/sub 3/O/sub 11/ is formed, which is dispersed on the SiO/sub 2/. MoO/sub 3/ crystals of various shapes occur at the surface of the dispersed phase. It is suggested that this catalyst is highly active in oxidizing acrolein to acrylic acid because of the presence of VMo/sub 3/O/sub 11/.
