Novel activated carbon-supported multi-metal oxides for peroxydisulfate activation and efficient organic pollutant degradation: insights into operations, transformation mechanism, and DFT study

Key Points

• The aim is to develop an efficient catalyst for activating peroxydisulfate to degrade organic pollutants like BPA.
• Synthesis of a catalyst by decorating CoFe2O4 and Fe3O4 nanoparticles onto activated carbon.
• Evaluation of catalyst efficiency in activating peroxydisulfate.
• Investigation of both radical and non-radical degradation mechanisms.
• The catalyst demonstrates high efficiency in degrading BPA.
• Both radical and non-radical mechanisms contribute to the degradation process.
• The novel catalyst can be easily recovered and reused.
