Toluene is an aromatic pollutant coming from a wide range of sources,which causes strong harm to human health and environment.Manganese oxide is considered as the most potential catalyst for oxidation of toluene due to its controllable morphology,diverse crystal structure and variable valence state.In this paper,the research progress of catalytic oxidation of toluene by manganese-based catalysts in recent years was reviewed,including single manganese oxide and composite manganese oxide.The effects of morphology,crystal structure,oxygen vacancy,metal-carrier interaction and other factors on the catalytic oxidation performance of toluene were discussed.The catalytic reaction mechanisms of toluene oxidation were also summarized.Finally,it is suggested that developing a simple synthesis process to construct MnO,or Mn-based composite nano-catalyst,and studying the actual factors affecting the catalyst behavior for industrial exhaust are the future research directions in this field.
