Abstract

Efficient catalysts for activating peroxymonosulfate (PMS) during advanced oxidation processes (AOPs) were essential for organic degradation efficiency. Herein, we reported the synthesis of N, S-doped FeCo bimetal oxides and phosphides nanoparticles-encapsulated porous carbon microspheres (FeCoO_X/FeCoP_X@C), where both nanoparticles and carbon microspheres act as active sites for the activation of PMS. The FeCoO_X/FeCoP_X@C and PMS system exhibited excellent organic catalytic degradation performances and its activation mechanism was proposed. For the first time, the activation of PMS was realized through nonradical and radical pathways simultaneously on FeCoO_X/FeCoP_X@C, which can be an extraordinary contribution for the design of efficient heterogeneous catalysts with superior degradation performance.
