Oxygen Defect Engineering of Hexagonal Perovskite Oxides to Boost Catalytic Performance for Aerobic Oxidation of Sulfides to Sulfones (Adv. Funct. Mater. 29/2025)

Oxygen Defect Engineering In article number 2425452, Keiju Wachi, Xuefeng Wang, and co-workers design Ru-substituted hexagonal perovskite SrMnO3, featuring face-shared oxygen species, as an effective heterogeneous catalyst for aerobic oxidation of sulfides. The catalyst demonstrates high selectivity to sulfones (≥99%) under mild reaction conditions (≥30°C). The cover represents that Ru substitution facilitates oxygen transfer to sulfides, analogizing Newton's cradle.
