Nanostructured ε-MnO₂ made up of its nanowhiskers was successfully prepared with KMnO₄ and MnSO₄ as the raw materials at room temperature.X-ray diffraction(XRD),transmission electron microscopy(TEM) and specific surface area(BET) were used to characterize the product.The as-prepared nano-structured ε-MnO₂ was used as a catalyst to decompose simulated phenol wastewater.This catalytic reaction was mild and required any oxidant.Based on fluorescence spectroscopy(FL) results,the removal of phenol was up to 80.4% within 80 min.The intermediate products during the degradation process of phenol were investigated with high performance liquid chromatography(HPLC).The possible decomposition path of phenol was proposed.Kinetic study of the catalytic reaction showed that the reaction kinetics order was 1.64 and the reaction rate constant was 0.007 5(mg·L^-1)^-0.64/min.
