Peroxymonosulfate-activated degradation of rhodamine B over one-dimensional H 2 Ti 3 O 7 /TiO 2 heterostructures: synergistic effects and the reaction mechanism

Key Points

• The study aims to investigate the degradation of rhodamine B using peroxymonosulfate activated by H2Ti3O7/TiO2 heterostructures.
• Used UV light to activate peroxymonosulfate (PMS).
• Generated reactive species through photoexcitation of the composite.
• Analyzed the degradation of rhodamine B to products like CO2 and H2O.
• Significant degradation of rhodamine B observed under UV light.
• PMS activated formation of sulfate radicals (SO4˙−), aiding degradation.
• Reactive species transformed adsorbed organics into harmless byproducts.
