Binary molybdenum oxides are active catalysts for propene oxidation to acrolein if they are structurally different from orthorhombic MoO 3 (o-Mo). The periodical structure of the as-synthesized precatalyst must be different from o-Mo to create the ac

The ternary oxide (MoVW)5O14 is considered to be highly significant for catalytic, mild selective oxidation reactions. By using UV/Vis, ESR and 95Mo NMR spectroscopies the coordination chem-istry of the molybdate species in the precursor solutions wa

The solid solution Cr2−xTixO3 is an excellent gas sensor material, with stability of performance over the short and long-term and minor influences of variations of humidity. It is the first new material to be successfully commercialised in large-vo

The different preparation steps are characterized to the single phase, crystalline, ternary oxide (MoVW) 5O14, which is important for catalytic, mild selective oxidation reactions. For the synthesis of this oxide, solutions of ammonium heptamolybdate
