Oxygen-free wastewater treatment system constructed using FeWO 4 @CN S-scheme heterojunction photocatalyst coupled with H 2 O 2 activation

Key Points

• To develop and evaluate an oxygen-free catalytic system for efficient degradation of antibiotic pollutants using a specific photocatalyst.
• Preparation of an S-scheme FeWO4 @CN catalytic system through in situ calcination.
• Activation of hydrogen peroxide (H2O2) via photothermal effects.
• Assessment of the system's efficiency in degrading antibiotic pollutants under specific conditions.
• The FeWO4 @CN system provided abundant active sites for catalytic reactions.
• Efficient activation of H2O2 led to stable degradation of contaminants.
• Photothermal effects enhanced the photocatalytic activity.
