Rhodium catalyst compounds

Patent Granted In 2012, 81% of the world production of rhodium was consumed to produce three-way catalytic converters.[25] Rhodium shows some advantages over the other platinum metals in the reduction of nitrogen oxides to nitrogen and oxygen:[30] 2 NO x → x O 2 + N 2 Rhodium-based catalysts are used in a number of industrial processes; notably, in the automobile catalytic converters and for catalytic carbonylation of methanol to produce acetic acid by the Monsanto process.
