The role of various oxygen species in Mn-based layered double hydroxide catalysts in selective alcohol oxidation

Precise identification of oxygen species in LDH-based catalysts was investigated for the first time for alcohol oxidation. Assisted by surface O2-, O-2 molecules were activated in various oxidation states. Labile oxygen species could react with alcohol except for the O-2(2-) immobilized by unsaturated metals, while other oxygen species only transferred oxygen species as mediators.
