Enhancing ibuprofen degradation in aqueous solutions: The synergistic role of bimetallic MOFs (Mn/ZIF-67) and modified graphene oxide in peroxymonosulfate activation

[Display omitted] •A novel Mn/ZIF-67@GO was rationally synthesized for PMS activation.•Mn/ZIF-67@GO + PMS system could remove 98 % of ibuprofen in 15 min.•The catalyst exhibited an eco-friendly solution and recyclability for water treatment.•The versatile Mn/ZIF-67@GO/PMS system effectively removed various antibiotics.•Radicals and non-radicals were involved in IBP degradation. An innovative bimetallic (Co and Mn) composite catalyst, Mn/ZIF-67@GO, was synthesized for effective peroxymonosulfate (PMS) activation and rapid degradation of ibuprofen (IBP). The Mn/ZIF-67@GO/PMS system demonstrates remarkable catalytic performance, achieving a 98 % degradation of a 0.05 mM IBP solution within 15 min. This high efficiency is maintained across a pH range of 5 to 9, with excellent system stability over five cycles, showing only minimal metal leaching (Co and Mn
