Engineering charge transfer via built-in electric field in Z-scheme heterojunction photocatalysts for antibiotic degradation in wastewater

Key Points

• Antibiotic degradation improves significantly with enhanced charge transfer in Z-scheme heterojunctions, indicating promising photocatalytic activity.
• The study shows that an engineered built-in electric field in photocatalysts boosts degradation rates by 35% under visible light.
• Assessment using a novel Z-scheme design reveals effective separation of charge carriers, leading to superior photocatalytic efficiency.
• These findings highlight the necessity for tailored photocatalysts in industrial wastewater treatment, aiming for practical environmental applications.
