Description
Summary:To improve the low photocatalytic efficiency, powerful UV light activation, and facile electron transport of ZnFe 2 O 4 –CuO the combination of different C 3 N 4 and N/B/RGO nanosheets in ZnFe 2 O 4 –CuO–C 3 N 4 and ZnFe 2 O 4 –CuO-N/B/RGO ternary nanoheterojunction fabricated that lead to decrease recombination of electron/hole pairs and high photocatalytic efficiency for degradation of MO organic pollutants. The ZnFe 2 O 4 , ZnFe 2 O 4 -N/B/RGO, CuO-N/B/RGO, ZnFe 2 O 4– CuO, ZnFe 2 O 4 –CuO-N/RGO, ZnFe 2 O 4 –CuO-B/RGO, ZnFe 2 O 4 –CuO-RGO, ZnFe 2 O 4 –CuO-N/B/RGO and ZnFe 2 O 4 –CuO–C 3 N 4 photocatalysts were fabricated by sol–gel technique using melamine, zinc nitrate, ferric nitrate and copper nitrate hexahydrate as precursors. The prepared ZnFe 2 O 4 –CuO–C 3 N 4 photocatalysts have a narrower bandgap than that of ZnFe 2 O 4 –CuO-N/B/RGO ternary heterojunction, resulting in higher photocatalytic activity for Fenton-type photodecomposition of methyl orange (MO). The activity of the compounds as a photocatalyst can be attributed to an electron transfer process on the surface of the photocatalyst, where the ZnFe 2 O 4 –CuO–C 3 N 4 is a powerful electron donor and electron acceptor for the oxidized MO under ultra-violet (UV) light irradiation. ZnFe 2 O 4 –CuO–C 3 N 4 ternary heterojunction photocatalyst show a red shift (lowest bandgap) in absorption and excellent photocatalytic degradation of MO. The particle sizes of ZnFe 2 O 4 and CuO nanoparticles (NPs) were in the ranges of ~ 650–750 and ~ 50–150 nm, respectively. The CuO and ZnFe 2 O 4 samples were displayed spherical and cubic morphology in FESEM images, respectively. Among the as-prepared nanostructures ZnFe 2 O 4 –CuO–C 3 N 4 show the highest photocatalytic activity and eliminate 95.84% (80 min) of methyl orange under UV light irradiation.
