Designing a NiFe-LDH/MnO2 heterojunction to improve the photocatalytic activity for NOx removal under visible light

Chemical Engineering Journal, Год журнала: 2024, Номер 489, С. 151241 - 151241

Опубликована: Апрель 12, 2024

2D/2D heterojunctions between ultrathin NiFe-CO3 layered double hydroxide (LDH) and varying amounts of birnessite (δ-MnO2) were prepared using an environmentally friendly cost-effective self-assembly method. The samples have proven to be efficient in their application, mitigating NOx emissions via a photooxidative process. effective creation NiFe–LDH/MnO2 has been verified through variety characterisation techniques, such as XRD, FT-IR, TGA, XFR, N2 adsorption–desorption isotherms, HRTEM SEM images, EDX, XPS. Photocatalytic measurements indicated that the heterojunction formed NiFe-LDH MnO2 modifies its photoconductive behaviour, significantly enhancing visible light photocatalytic performance partners. Finally, optimal relationship process was studied. It found ratio 10:1, respectively, exhibited superior properties compared other composites, highlighting best degradation NO under notable stability during recycling
