ABSTRACT:
A multimetal oxide of the formula I,in-line-formulae description="In-line Formulae" end="lead"?Aga-cQbMcV2Od*e H2O,  Iin-line-formulae description="In-line Formulae" end="tail"?where a is from 0.3 to 1.9, Q is an element selected from among P, As, Sb and/or Bi, is from 0 to 0.3, M is a metal selected from among Nb, Ce, W, Mn, Ta, Pd, Pt, Ru and/or Rh, c is from 0.001 to 0.5, with the proviso that (a-c)≧0.1, d is a number which is determined by the valence and abundance of the elements other than oxygen in the formula I and e is from 0 to 20, and also precatalysts and catalysts produced therefrom for the partial oxidation of aromatic hydrocarbons are described.
