A. Martin et al., SYNTHESIS OF CO AND V-CONTAINING ALPO4-5 MOLECULAR-SIEVES AND CHARACTERIZATION OF THEIR ACID PROPERTIES, Reaction kinetics and catalysis letters, 56(1), 1995, pp. 37-46
Co and V-containing AlPO4-5 molecular sieves were characterized by IR
spectroscopy and TPDA. The incorporation of Co2+ leads to the formatio
n of additional P-OH groups. The introduction of V4+ on T-atom positio
ns could not be observed and it seems that the VO2+ ions are only fixe
d by interaction with terminal OH-groups.
