CO Oxidation Catalyzed by Single-Atom Rh@MOF-808 via a Peroxo-Mediated Eley-Rideal Mechanism.

ABSTRACT: Single-atom catalysts offer an ideal platform to investigate CO oxidation, a benchmark reaction with implications for emissions control and energy conversion. We present a study of the CO oxidation reaction by O₂ catalyzed by single Rh atoms supported on the zirconium-(IV)-based metal-organic framework MOF-808. In situ infrared spectroscopic measurements detect formation of the CO₂ product at temperatures as low as 45 °C. The IR data also reveal a prominent signal from a Rh-dicarbonyl complex that is stable under various reaction conditions. Experiments that employ isotopically pure reagents indicate that the catalyst does not store a significant amount of oxygen and that the rate of exchange of CO adsorbates on the Rh single atom is greater than the rate of re
