Ammonia (3 of 3) (IMAGE) Rice University Caption The addition of cobalt atoms to fill vacancies in 2D molybdenum disulfide crystals enhances the material's ability to catalyze ammonia from dinitrogen. Rice University scientists have developed a "green" method for the small-scale synthesis of ammonia that uses less energy and produces less carbon dioxide than industrial processes.
