摘要: The invention concerns solids comprising a single tungsten oxide layer on a zirconia support and/or titanium dioxide support, characterized in that the tungsten exhibits tetrahedral co-ordination, before and after calcining. The invention also concerns the method for preparing the solids, and their uses as acid catalysis reactions catalyst.
