The present invention relates to monolith catalysts comprising a catalytic metal deposited onto a coated monolith substrate comprising a wash coat applied to a monolith substrate wherein the monolith catalysts have a surface area ranging from 0.1 to 25 m.sup.2/gram as measured by adsorption of N2 or Kr using the BET method. The invention also relates to the coated monolith substrates used in such monolith catalysts. The monolith catalysts of the present invention are particularly suited toward use in hydrogenation processes which employ an immiscible mixture of an organic reactant in water.
