Al-Ni-Mo catalysts produced by mixing of NiMoO{sub 4} and alumina hydrooxide (psevdobemit) were investigated by UV reflectance spectroscopy and combination scattering spectroscopy. The catalysts without H{sub 3}PO{sub 4} additives are characterized by destruction of NiMoO{sub 4} and interaction between Ni, Mo had the support with formation of surface Al-Ni-Mo structures. The study of H{sub 3}PO{sub 4} additives effect on the formation of oxide Ni-Mo phases in the Al-Ni-Mo catalysts has shown, that the introduction of H{sub 3}PO{sub 4} allows to stabilize NiMoO{sub 4} and to prevent its decomposition.
