Isolated Pd atoms supported on high surface area MnO 2 , prepared by the oxidative grafting of (bis(tricyclohexylphosphine-palladium(0)), catalyze (>50 turnovers, 17 h) the low temperature (≤325 K) oxidation of CO (7.7 kPa O 2 , 2.6 kPa CO) with results of in situ / operando and ex situ spectroscopic characterization signifying a synergistic role of Pd and MnO 2 in facilitating redox turnovers.
