The promotion effect of isolated potassium atoms with hybridized orbitals in catalytic oxidation.

چکیده
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.
