Abstract

The nature of the promotion effect of isolated potassium atoms anchored on surfaces of a Hollandite manganese oxide was investigated by studying their geometric and electronic structures. The results reveal that the surface isolated potassium atoms with hybridized d–sp orbitals specifically promote oxygen activation, so enhancing the low-temperature reactivity in catalytic oxidation.
