In this work, we compare the CO oxidation performance of Pt single atom catalysts (SACs) prepared via two methods: (1) conventional wet chemical synthesis (strong electrostatic adsorption-SEA) with calcination at 350 °C in air; and (2) high temperature vapor phase synthesis (atom trapping-AT) with calcination in air at 800 °C leading to ionic Pt being trapped on the CeO<sub>2</sub> in a thermally stable form. As-synthesized, both SACs are inactive for low temperature (<150 °C) CO oxidation. Afte ...[more]
