Facile fabrication of g-C3N4 supported Fe3O4 nanoparticles/ZnO nanorods: A superlative visible light responsive architecture for express degradation of pantoprazole

Mechanism of visible photon absorption: unveiling of the C3N4–ZnO photoactive interface by means of EPR spectroscopy

“…TEM imaging confirmed the homogenous distribution of the two phases and their anchoring one around the other, suggesting an active partnership at the interface and constituting a heterojunction system. In the last years, several authors have reported the prominent photocatalytic ability upon visible light exposure of the mixed C 3 N 4 -ZnO material, 47,49,54,108,109 where they speculated the working mechanism at the interface of the heterojunction. In most of the cases, the sustained hypothesis of the real process upon visible photonic irradiation foresees an electron transfer from the C 3 N 4 conduction band (À1.12 eV vs. NHE) to the ZnO conduction band (À0.02 eV vs. NHE), typical of a type-II heterojunction or a p-n heterojunction.…”

ZnO nanostructured materials and their potential applications: progress, challenges and perspectives

“…(Reproduced from [269] with permission from American Chemical Society Publisher.) (Reproduced from [292] with permission from Elsevier Publisher.) Due to the small thickness of the nanobelts, spontaneous polarization normal to the nanobelt leads to the growth of helical nanostructures.…”

“…An excess of Zn was deemed to cause recombination of photo-induced charges that led to decreased photocatalytic efficiency. In a recent investigation by the authors of the current work, 292 a destructive photocatalyst made up of ZnO nanorods/Fe 3 O 4 nanoparticles anchored onto g-C 3 N 4 sheets was synthesized using hydrothermal synthesis and ultrasonication techniques. HRTEM micrographs shed light on the coupling of Fe 3 O 4 nanoparticles with ZnO nanorods and the successful formation of the intended ternary heterojunction.…”

Green synthesis of sulfur‐doped g‐C3N4 nanosheets for enhanced removal of oxytetracycline under visible‐light irradiation and reduction of its N‐nitrosodimethylamine formation potential

“…SCN nanosheets successfully captured visible light and produced holes (h + ) and electrons (e − ) in the VB and the CB (Eqn (6)) 40 . On the one hand, the e − produced from SCN reacts with O 2 adsorbed on the surface of SCN to generate • O 2 − (Eqn (7)); and then • O 2 − reacts with H + or with H + and O 2 in the solution to produce • OH (Eqns (8)–(10)).…”
