Synergistic interface engineering in ZnO@CNT catalysts: electronic modulation for switching peroxydisulfate activation toward a 1 O 2 -dominated non-radical pathway

Key Points

• This research aims to explore the efficiency of ZnO@CNT catalysts in activating peroxydisulfate for singlet oxygen production.
• Synthesis of ZnO@CNT catalysts
• Activation of peroxydisulfate (PDS)
• Assessment of singlet oxygen generation
• Evaluation of SMX removal from water
• ZnO@CNT effectively activates PDS to produce singlet oxygen
• Significant reduction of SMX concentration in water
• Demonstrated potential for non-radical pathways in pollutant degradation
