Novel face-centered, cubic molybdenum oxycarbonitride catalyst and compositions are described together with a general method of synthesis. The compositions can be obtained by the relatively low temperature thermal decomposition of an amine molybdate and can be amorphous, poorly crystalline, or substantially crystalline, and can unexpectedly possess high surface areas in the region of about 130 m<2>/g and higher. The crystalline compositions have the general formula: MoOaCbNc, where a, b, and c are non-zero decimal values and the sum: a + b + c, is less than or equal to about one, as shown by x-ray diffraction and chemical analyses. The compositions are useful as catalysts in producing hydrocarbons from the reaction of CO and H2, and CO and steam, and also in producing ammonia from the catalyzed reaction between N2 and H2. |
