Peroxymonosulfate Activation by Facile Fabrication of α-MnO for Rhodamine B Degradation: Reaction Kinetics and Mechanism.

The persulfate-based advanced oxidation process has been an effective method for refractory organic pollutants' degradation in aqueous phase. Herein, α-MnO with nanowire morphology was facially fabricated via a one-step hydrothermal method and successfully activated peroxymonosulfate (PMS) for Rhodamine B (RhB) degradation. Influencing factors, including the hydrothermal parameter, PMS concentration, α-MnO dosage, RhB concentration, initial pH, and anions, were systematically investigated.
