Mn(1)-Co/TiO2 catalyst exhibited a good catalytic performance for DBM oxidation.
The redox cycle (Co2+ + Mn4+ ↔ Co3+ + Mn3+) existed over Mn(1)-Co/TiO2 catalyst improved the redox property of the catalyst.
The reaction mechanism for catalytic oxidation of DBM over Mn-Co/TiO2 catalysts was proposed.
