Hydrogen Bonds and In situ Photoinduced Metallic Bi⁰/Ni⁰ Accelerating Z‐Scheme Charge Transfer of BiOBr@NiFe‐LDH for Highly Efficient Photocatalysis

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(41)

Published: July 8, 2024

For heterojunction system, the lack of stable interfacial driving force and definite charge transfer channel makes separation efficiency unsatisfactory. The photoreaction mechanism occurring at interface also receives less attention. Herein, a 2D/2D Z-scheme junction BiOBr@NiFe-LDH with large-area contact featured by short hydrogen bonds strong electric field (IEF) is synthesized, in situ photoinduced metallic species assisting demonstrated. between O atoms from BiOBr H NiFe-LDH induce significant redistribution, establishing robust IEF. Notably, during photocatalytic reaction, Bi

Heterogeneous photocatalysis–self-Fenton technology is a sustainable strategy for treating organic pollutants in actual water bodies with high-fluent degradation and high mineralization capacity, overcoming the limitations of safety risks caused by adding external iron sources hazardous chemicals homogeneous Fenton reaction injecting high-intensity energy fields photo-Fenton reaction. Herein, photo-self-Fenton system based on resorcinol–formaldehyde (RF) resin red mud (RM) was established to generate hydrogen peroxide (H2O2) situ transform into hydroxy radical (•OH) efficient tetracycline (TC) under visible light irradiation. The capturing experiments electron spin resonance (ESR) confirmed that hinge enhanced performance this superior H2O2 yield (499 μM) through oxygen reduction process (ORR) two-step single-electron over concentration •OH due activation effect RM. In addition, Fe2+/Fe3+ cycles are accelerated photoelectrons effectively initiate Finally, possible pathways were proposed via liquid chromatography-mass spectrometry (LC-MS). This study provides new idea environmental recovery waste-based heterogeneous photocatalytic self-Fenton system.
