Various MnO₂ structures have been extensively applied in catalysis. In this study, γ-MnO₂, α-MnO_2, and δ-MnO₂ with corresponding rod, tube, and hierarchical architecture morphologies were prepared and applied for the catalytic oxidation of chlorobenzene (CB). The redox ability, H₂O activation behavior, and acidity of MnO₂ were analyzed using a range of techniques, including TPR, H₂O-TPD, XPS, and pyridine-IR. The catalytic activities in CB oxidation were assessed; this revealed that γ-MnO₂ exhibited the highest activity and best stability, owing to its enriched surface oxygen vacancies that functioned to activate O₂ and H₂O, and capture labile chlorine, which reacted with dissociated H₂O to form HCl. All the MnO₂ phases generated toxic polychlorinated by-products, including CHCl₃, CCl₄, C₂HCl₃, and C₂Cl₄, indicating the occurrence of electrophilic chlorination during CB oxidation. In particular, the dichlorobenzene detected in the effluents of α-MnO₂ might generate unintended dioxins via a nucleophilic substitution reaction.
