Compositions and methods for the preparation of ZPGM catalytic converters are disclosed. Addition of Mn to ZPGM catalytic converters from prior ZPGM catalytic may create a new ZPGM catalytic converter with greater improvement TWC conditions compared to previous types. Suitable known in the art chemical techniques, deposition methods and treatment systems may be employed in order to form the disclosed ZPGM catalyst systems. Disclosed ZPGM TWC systems in catalytic converters may be employed to decrease the pollution caused by exhaust from various sources, such as automobiles, utility plants, processing and manufacturing plants, airplanes, trains, all-terrain vehicles, boats, mining equipment, and other engine-equipped machines. |
