Z-scheme NiFe LDH/Bi4O5I2 heterojunction for photo-Fenton oxidation of tetracycline

Chenxi Zhu et al.

Summary: Designing efficient catalysts for photo-Fenton organic contaminant degradation is crucial in addressing environmental deterioration and energy crises. In this study, we successfully synthesized a highly effective and stable Z-scheme NiFe LDH/Bi4O5I2 catalyst for tetracycline (TC) photodegradation. The optimized catalyst demonstrated over 95% TC degradation efficiency under visible light irradiation. It exhibited excellent stability, low metal ions leaching, and wide pH applicability, making it a potential candidate for TC elimination. The enhanced performance can be attributed to the Z-scheme heterojunction and accelerated H2O2 decomposition, facilitating the synergy between photocatalysis and Fenton reaction. This work provides insights for designing Z-scheme catalysts for photo-Fenton degradation of organic contaminants and other solar energy applications.

Xin Wang et al.

Summary: The development of efficient sonocatalysts is essential for treating antibiotic wastewater. In this study, an S-scheme sonocatalyst Cu2O/BiFeO3 was synthesized, where Cu2O nanoparticles were grown on the surface of BiFeO3.

Thickness-dependent piezo-photo-responsive behavior of ZnAl-layered double hydroxide for wastewater remediation

Jiayue Hu et al.

Summary: This study investigates the piezo-photocatalytic performance of different thicknesses of ZnAl layered double hydroxides (ZnAl-LDHs) in the degradation of CBZ pollutants. The results show that ultra-thin ZnAl-LDHs sheets exhibit higher efficiency and faster degradation rate, which can be attributed to their increased sensitivity to light irradiation and external stress. Additionally, the piezo-photocatalytic reaction of the ultra-thin ZnAl-LDHs is significantly enhanced compared to individual piezocatalysis and photocatalysis, due to the piezoelectric field's ability to boost the separation of electron-hole pairs and modulate band energy alignment.
