It has been demonstrated by IR spectroscopy that the irradiation of samples of V/sup 5 +//SiO/sub 2/, V/sup 5 +//Al/sub 2/O/sub 3/, and Ni/sup 2 +//Al/sub 2/O/sub 3/ in an atmosphere of D/sub 2/ causes the isotope replacement of hydrogen atoms of the hydroxyl groups on the surface of the support and results in the formation of OD groups on photoinduced V/sup 4 +/O/sup -/ sites. Molecules of CO are photosorbed both on reduced ions of transition metals in the form of M-CVertical BarO surface carbonyls and on O/sup -/ ions. In the latter case, CO/sub 2/, which is easily desorbed from V/sup 5 +//SiO/sub 2/, but is tightly bound to V/sup 5 +//Al/sub 2/O/sub 3/ owing to the chemisorption on the surface of the support, is formed on the samples containing vanadium.
