ABSTRACT:
A catalyst comprising nickel on a TiO2support is obtainable by coprecipitation ofnickel andat least one further metal selected from among Si, Zr, Hf, alkaline earth metals, Y, La and Ce, andoptionally at least one dopant metal selected from groups 5 to 11 of the Periodic Table of the Elements,from a solution in which the corresponding metal salts are present onto a particulate TiO2support, subsequent drying, calcination and reduction and optionally passivation to give the nickel-containing catalyst.It is used, in particular, for the hydrogenation of nitroaromatic compounds.
