Abstract:
1. A multimetal oxide material of the stoichiometry I where M M M a is from 0.01 to 1; b is from >0 to 1, c is from >0 to 1, d is from >0 to 0.5 and n is a number which is determined by the valency and frequency of the elements other than oxygen in (I), whose X-ray diffraction pattern has reflections h, i and k whose peaks are at the diffraction angles (2⊖) 22.2±0.5° (h), 27.3±0.5° (i) and 28.2±0.5° (k), the intensity P R=P and the FWHH of the reflection i and of the reflection k is in each case≦1°, wherein the at least one multimetal oxide material (I) is one whose X-ray diffraction pattern has no reflections with a peak i position 2⊖=50.0±0.3°.
