The direct Z-scheme Ag4V2O7/Ag3VO4/GO (AVGZ) nanostructure was successfully synthesized using a hydrothermal method with microwave-assisted techniques. obtained AVGZ catalyst characterized by XRD, TEM, EDX, UV-Vis, PL, and XPS methods. characterization results showed that under controlled pH conditions, the orderly stacking of vanadium oxide tetrahedron formed Ag4V2O7 nanoparticles (NPs) on surface Ag3VO4 nanorods (with diameter 50-200 nm). Interestingly, exhibited absorbance in visible light region at 470-550 nm wavelengths. photocatalytic performance evaluated degradation dichloro-diphenyl-trichloroethane (DDT) LED irradiation. Compared to Ag3VO4/Ag4V2O7 material, much higher activity DDT same reaction conditions. optimal conditions were determined be concentration 0.5 g L-1, 6.0, time 4 hours, achieving efficiency 95.46%, according analysis response methodology (RSM) based central composite design (CCD) method. compared Ag3VO4/GO (89.4%) (82.1%), respectively. Scavenging experiments conducted study mechanism spin trapping technique (EPR). indicated ·OH ·O2 - radicals primary oxidizing agents process catalyst. formation heterojunction addition GO accelerated electron-hole pair separation, enhancing durability photocatalysts. Furthermore, photocatalyst also proposed, demonstrating its potential application for light.

Facilitating the separation of photogenerated charges is a crucial process in photocatalytic degradation pollutants. In this study, Bi2O3/In2O3 composites were prepared using co-precipitation method and subsequently calcined at 400 ℃ for 1 h. The Mott-Schottky curves confirmed p(Bi2O3)-n(In2O3) heterojunction was yielded. Due to significant difference Fermi levels between Bi2O3 In2O3, an internal electric field established interface, with lines directed from In2O3 Bi2O3. Under illumination, excited electrons accumulated conduction band (CB) while holes gathered valence (VB) Bi2O3, promoting charge enhancing quantum efficiency. composite material exhibited highest activity when atomic percentage Bi 1:1, first-order reaction rate constant BI-1 increasing 0.0149 min−1, which 4.3 4.4 multiples higher than that pure Recycling experiments demonstrated possesses good reusability structural stability.
