A high-efficiency γ-MnO2-like catalyst in toluene combustion

A novel γ-MnO2 catalyst obtained by selective removal and other traditional MnO2 catalysts (α-, β-, δ-MnO2) were studied for their catalytic performance in toluene combustion. The new γ-MnO2 catalyst showed the best catalytic activity owing to its three-dimensional macroporous and mesoporous morphology and the γ-MnO2-like structure.
