摘要：

Molybdenum and cobalt based heteropolyanions (HPAs) could be used as an alternative to the conventional ammonium heptamolybdate and cobalt nitrate starting materials for friendly environmental preparation of Co-Mo/ Al2O3 hydrotreating catalysts. In this aim, cobalt salts of molybdocobaltate and molydboaluminate Anderson HPAs have been synthesized and characterized by TGA, XRD, XAS, and vibrational spectroscopies. The crystal structure refinement provided evidence for the formation of a new heteropolyoxomolybdate derived from the well-known Anderson structure.
