Mixture of oxides containing at least one solid solution of Al2O3 and TiO2 in one another, in which case the mixture of oxides has 0.5 to 45 molar, preferably 1 to 40 molar, particularly preferably 2 to 40 molar of Al and pores with a pore diameter d50 according to BJH between 2 and 50 nm, preferably between 2 and 40 nm, particularly preferably between 2 and 20 nm, and the specific surface area of the oxide mixture according to BET is found between 5 and 800 m2 / g, preferably between 30 and 600 m2 / g, particularly preferably between 50 and 450 m2 / g, characterized in that the logarithmic distribution of pore diameters has a width σ at most of 0 , 40, particularly preferably between 0.05 and 0.40 and the d50 particle size of the solid solution is 0.5 to 10 μm. |
