A catalyst support obtainable by a process for manufacturing a porous inorganic oxide comprising the steps of: (a) forming a silica-titania cogel hydrogel by coprecipitation of a titanium compound with silica; (b) aging said cogel under conditions of substantially neutral pH at a pH of 5 to 8, however, excluding a pH of 8, and at a temperature of 15 to 95 ° C for a time of at least 1 hour; (c) aging the aged cogel in this way to neutral pH under alkaline pH conditions in an aqueous solution with a pH in the range of 8 to 12 pH units, for a time in the range of 1 to 50 hours, at a temperature in the range of 70 to 120 ° C; and (d) drying the aged cogel in this manner twice to form a xerogel by drying in an oven, spray drying or azeotropic distillation drying. |
