The catalysts are generally useful for the selective hydrodeoxygenation of carboxylic acids containing at least one additional hydroxyl group along the backbone thereof. More particularly, the catalysts are sup - ported catalysts comprising platinum and rhodium, wherein the molar ratio of platinum to rhodium is in the range of about 3:1 to about 1:2. The average pore diameter of the cata­ lyst supports is in the range of from about 5 nm to about 70 nm and the surface area is in the range of from about 15 m /g 2 to about 200 m /g. 2 Also disclosed are methods for the hy­ drodeoxygenation of carboxylic acids, mono- and/or di-lac- tones thereof having at least one hydroxyl group on the back­ bone thereof to corresponding acids where the backbone hy­ droxyl group has been reduced in the presence of the catalyst. Further disclosed is a process of producing an adipic acid product at a yield of at least about 80%.
