Heteroatom doping in nanomaterials can import new active sites and promote catalytic activity. Here we report that Mn-doped Co3O4 nanorods (Mnx-Co3O4) via substituting Mn3+ (t2g3-eg1) for Co3+ (t2g6-eg0) exhibit ~100% yield for 4-Me benzyl alc. dehydrogenation catalysis at 60°C and no decay (8 cycles), compared with only 1.4% of activity for bare Co3O4 catalysts. We characterize the fine structures of Mnx-Co3O4 at the at. level and demonstrate that the superior catalytic performance is strongly related to the Mn3+-induced Jahn-Teller (J-T) effect, which is a geometric distortion that has generally been considered to be disadvantageous for applications. Exptl. observations and theor. calculations reveal that unsaturated Mn3+ with J-T distortion acts as an active site, and readily reacts with -OH groups of benzyl alc. adsorbed nearby, simultaneously promoting dehydrogenation to directly yield benzaldehyde. Mnx-Co3O4 catalysts rapidly dehydrogenate alcs. into aldehydes/ketones for 19 reactions with >99.9% selectivity and 14 examples with >90.2% yield. Mn3+-induced Jahn-Teller effect in Mn-doped Co3O4 catalyst promotes sustainable catalytic dehydrogenation of alcs.
