Acceleration of peroxymonosulfate decomposition by a magnetic MoS2/CuFe2O4 heterogeneous catalyst for rapid degradation of fluoxetine

•CuFe2O4 was uniformly doped onto MoS2 to activate peroxymonosulfate.•Hydroxyl radicals and sulfate radicals were the major reactive oxygen species.•Efficient degradation was ascribed to the rapid decomposition of peroxymonosulfate.•Nine intermediates involving hydroxylation and open-chain or -ring were detected.
