Abstract: The invention relates to a catalyst, which may be produced by reduction of a hydrogenation-active metal precursor, optionally on an oxidic support, by means of reaction with at least one compound of general formula (I): HnM (OR)3-n, where M = Ga or Al, R = CR`3 or SiR`3, where R` = C1-20 alkyl and n = 1 or 2, or dimers or oligomers thereof, whereby the crystal size of the hydrogenation-active metal in the prepared catalyst is 5 to 30 nm. The catalysts are used for the hydrogenation of aromatic nitro compounds to give aromatic amines, reductive amination, dehydrogenation and isomerisations.
