Under oxygen adsorption, a cobalt-O-2 species with an O-O band at 1019
cm(-1) and a paramagnetic superoxo-cobalt (Co-O-O) species with O-O a
nd Co-O bands at 1048 and 467 cm(-1) have been observed on calcined an
d reduced CoAPO-11 molecular sieve samples, respectively, by Raman spe
ctroscopy. The stretching modes of superoxo-cobalt have also been conf
irmed by O-16(2)/O-18(2) substitution.
