Abstract
Cu ions were deliberately introduced into the tetrahedral sites of MnCo spinel oxides by pyrolysis of Prussian blue analogues pre-doped with Cu. The as-synthesized catalysts deliver superior catalytic activity for toluene oxidation and excellent stability owing to the increase of octahedral metal ions and elongation of metal-oxygen bonds induced by the specific substitution of Cu.
