Oxidation ZPGM catalyst systems and three way ZPGM catalyst systems are disclosed. ZPGM catalyst systems may oxidize toxic gases, such as carbon monoxide and hydrocarbons, optionally some ZPGM catalyst systems may as well reduce nitrogen oxides that may be included in exhaust gases. ZPGM catalyst systems may include: a substrate, a washcoat, and an overcoat. The washcoat may include at least one ZPGM catalyst and carrier material oxides. Similarly, overcoat may include at least one ZPGM catalyst, carrier material oxides and OSMs. Suitable known in the art chemical techniques, deposition methods and treatment systems may be employed in order to form the disclosed ZPGM catalyst systems.
