Carbon Dot Loaded Integrative CoFe2O4/g‐C3N4 P‐N Heterojunction: Direct Solar Light‐Driven Photocatalytic H2 Evolution and Organic Pollutant Degradation

“…After the heterojunction formation, the whole energy levels of the CoFO increased, while the g‐CN energy levels get decreased. Now, the conduction band of the g‐CN lies below the conduction band of the CoFO . This p‐n heterojunction formation leads to electron transfer from CoFO to g‐CN under solar light irradiation.…”

“…Owing to its wide bandgap energy, it only harvests the UV light from the whole spectrum of solar light. Therefore, it motivates the research towards the development of visible light active photocatalysts for energy and environmental remediation application . Among various visible light photocatalysts, the graphitic phase carbon nitride (g‐C 3 N 4 ) has attracted the researchers in the field of organic pollutant degradation and hydrogen production by photocatalysis process.…”

Structural, Magnetic, and Optical Studies of Ni–Mg Ferrites Synthesized by Polyol Method

“…Similar results are reported by Liu et al [ 55 ] and Jose‐Luis et al [ 56 ] This strong band at 746 nm is due to the charge transfer interaction between Fe‐3 d , an empty state of the valance band, and the dominated O‐2 p , an occupied state of conduction band [ 57 ] and the Ni 2 + –O – Fe 3 + ‐to‐Ni + –O–Fe 4 + transitions.

Construction of rGO Supported Integrative NiFe2O4/g‐C3N4 Nanocomposite: Role of Charge Transfer for Boosting the OH. Radical Production to Enhance the Photo‐Fenton Degradation

“…[2][3][4] The diffraction peaks of NFO was positioned at 18.47°, 30.28°, 35.68°, 37.27°, 43.31°, 54.09°, 57.26°, and 62.88°are assigned to the planes (111), (220), (311), (222), (400), (422), (511) and (440) which is well-matched with the previous report and JCPDS ). [20] The characteristic peak at 10.63°ascribed the plane (001) of graphene oxide (GO). [13] The diffraction pattern of binary and ternary composite photocatalysts was shown in Figure 1(b).…”

“…The XPS peak at a binding energy of 529.76 eV described the O 2À ion in the NFO crystal system, whereas the peak positioned at 531.6 eV attributed to the oxygen vacancy in NFO (or) surface adsorbed hydroxyl group (OHÀ C=O bond) in rGO. [3][4][5][18][19][20] Indeed, the interaction between the nanosheets (g-CN/rGO) and nanoparticle was investigated by the XPS analysis and it is well-matched with the HRTEM and FTIR results.…”
