Conversion of Methane with Oxygen to Produce Hydrogen Catalyzed by Triatomic Rh₃ ^- Cluster Anion.

ABSTRACT: Metal catalysts, especially noble metals, have frequently been prepared upon downsizing from nanoparticles to subnanoclusters to catalyze the important reaction of partial oxidation of methane (POM) in order to optimize the catalytic performance and conserve metal resources. Here, benefiting from mass spectrometric experiments in conjunction with photoelectron spectroscopy and quantum chemical calculations, we successfully determine that metal cluster anions composed of only three Rh atoms (Rh₃ ^-) can catalyze the POM reaction with O₂ to produce 2H₂ + CO₂ under thermal collision conditions (∼300 K). The interdependence between CH₄ and O₂ to protect Rh₃ ^- from collapse and to promote conversio
