Disclosed are novel catalysts useful for the hydrogenation of carbonyl-containing compounds at mild conditions of temperature and pressure to produce alcohols or amines is disclosed. The catalysts comprise palladium and zinc on a catalyst support material and are obtained by the steps of: (a) providing a catalyst support material on which is deposited zero-valent palladium in a uniformly and highly dispersed form; (b) contacting the palladium-bearing support material of (a) with zinc or a reducible compound thereof; and, preferably, (c) heating the palladium- and zinc-bearing support of (b) at a temperature of about 200 DEG to 400 DEG C. in the presence of an oxygen-containing gas.
