Catalytic activation of peroxydisulfate by alfalfa-derived nitrogen self-doped porous carbon supported CuFeO2 for nimesulide degradation: Performance, mechanism and DFT calculation

[Display omitted] •CuFeO2/NPC composites were prepared at no nitrogen sources and reductant.•CuFeO2/NPC can effectively activate PDS to degrade nimesulide.•The OH, SO4- and 1O2 were the main reactive species for nimesulide degradation.•Mechanism of PDS activated by CuFeO2/NPC was clarified in detail...
