Single-atom copper catalyst for the S-arylation reaction to produce diaryl disulfides.

ABSTRACT: Single-atom Cu supported on CeO _x nanorod catalysts (Cu₁/CeO _x ) have been synthesized through the anchoring of copper by terminal hydroxyl groups on the CeO _x surface. The oxygen defect characteristics of the CeO _x nanorods promote electron transfer between Cu and CeO _x through a Ce-O-Cu interface, which realizes flexible electronic regulation of the Cu sites. Single-atom Cu species with an oxidation state of between +1 and +2 were formed, which was confirmed by X-ray photoelectron spectroscopy, X-ray fine structure spectroscopy, and electron paramagnetic resonance spectroscopy. Cu₁/CeO _x emerged as a catalyst with advanced catalytic performance for elemental s
