Platinum group metal (PGM) catalysts are the current standard for control of pollutants in automotive exhaust streams. In spite of their high cost, PGM catalysts exhibit low catalytic activities for CO oxidation at low temperatures (&lt;200 °C) because of inhibition by hydrocarbons in exhaust streams. Here we present nanostructured ternary and high entropy oxide catalysts that potentially outperform commercial PGM catalysts for CO oxidation in simulated exhaust streams and other energy-related oxidative catalysis reactions. The synthesis strategies toward various nanostructured multi-component oxide catalysts as well as that using the entropy maximization will be discussed. In conclusion, these nanostructured multi-component oxide catalysts show great potential as a low-cost component for various low-temperature oxidative processes.<br/>
