Insights into the degradation of 2,4-dichlorophenol in aqueous solution by α-MnO2 nanowire activated persulfate: catalytic performance and kinetic modeling

α-MnO₂ nanowires were synthesized through a hydrothermal method. Sulfate and hydroxyl radicals were produced in α-MnO₂-activated persulfate system to degrade 2,4-dichlorophenol.
