| 摘要 |
A process for preparing W, Mo or mixed metal oxides thereof by oxidizing a reduced metal oxide of the formula (NHmR4-m)q+MOp where each R is independently C1-C20 aliphatic, C7-C14 araliphatic or C3-C8 cycloaliphatic with the proviso that adjacent R's, together with the nitrogen atom to which they are attached, may form a 5, 6 or 7 membered heterocyclic ring, m is an integer from 0 to 4, q is a number from about 0.001 to 1/3, M is W or Mo and p is a number from 2 to 3 with aqueous hydrogen peroxide. The so-treated reduced metal oxide is isolated and heated in an oxygen containing atmosphere to form metal oxides of the formula MOp.
