A solid, particulate catalyst composition is provided containing an active nickel component in which the nickel constitutes from about 25 to about 60 wt % of the catalyst composition; a molybdenum component in which the molybdenum constitutes from about 5 to about 20 wt % of the catalyst composition; and a binder component comprising at least one of oxides of silica, zirconium, aluminum, zinc and calcium, each of the calcium, aluminum and zinc being present in an amount no greater than about 2 wt %, preferably about 0 to 1 wt %. The catalyst is designed for the selective hydrogenation of 3-hydroxypropanal to 1,3-propanediol in aqueous solution.
