“…On the other hand, the diffraction peaks of NFO also slightly shifted to the lower angel side which described the crystallinity of NFO nanoparticles are affected by the carbon nitride. [4,5] The XRD pattern of the ternary nanocomposite also shows a similar pattern as like as NFO/g-CN nanocomposite. The invisible of typical rGO diffraction peak in the ternary nanocomposite attributed to the low concentration of rGO or very low diffraction intensity.…”

“…Several strategies have been developed to improve the photocatalytic efficiency of carbon nitride. [5] On the other hand the recovery and recycle processes also restrict the photocatalytic efficiency of the bare carbon nitride. The active site of the photocatalysts is reduced during the filtration and centrifugation processes, which leads to low catalytic efficiency.…”

“…In addition to this, the magnetic materials have significant photocatalytic activity, which makes them the best auspicious material in the photocatalysis system. [5,6] Among various magnetic materials, the cubic structural spinel metal ferrites (MFe 2 O 4 ) have paid great attention to photocatalysis. In the spinel system, the oxygen ions are occupied in the face-centered phase and the metal ions are occupied within the spaces.…”

The facile sol‐gel and hydrothermal method have been used to prepare the ternary heterojunction of rGO supported NiFe2O4/g‐C3N4 nanocomposite. The structural, morphological, optical, magnetic, and charge transport properties of the prepared nanoparticles were analyzed by various analytical methods. The supportive rGO helps to harvest the more amount of visible light and helps to electron transformation was confirmed by UV‐vis‐DRS and PL spectroscopy studies. The rGO acts as an electron transport supporting layer for enhancement of radical production for effective dye degradation reaction under LED and sunlight irradiation. In particular, 10GO/NFO/g‐CN ternary nanocomposite exhibits the highest photo‐Fenton degradation when compared to other photocatalysts. They produced a large amount of OH• radicals that were beneficial for the photocatalytic process. The possible reaction mechanism and the active species for the dye degradation process were investigated by elemental trapping experiment and TA test. The recycling process proves the stability of the prepared photocatalyst. Hence, the reported ternary heterojunction could be a superior candidate for environmental remediation applications.

In this report, the novel carbon dot (CD) loaded CoFe2O4/g‐C3N4 p‐n heterojunction for photocatalytic H2 evolution and tetracycline (TCN) degradation under sunlight irradiation has been proposed. The wet chemical method was used to prepare the photocatalysts. The heterojunction formation between the CoFe2O4 and g‐C3N4 facilitates to improve the solar light absorption ability which was confirmed by UV‐vis‐diffused reflectance spectroscopy. Moreover, the CD loading improves the charge carrier's separation. Comparison with the pure and binary nanocomposite photocatalysts, the CD loaded ternary heterojunction photocatalyst exhibits the greater photocatalytic performance with high H2 production (2715 μmol/g) and TCN degradation (95 %) under sun‐light irradiation. Moreover, the recycling process shows the excellent stability nature of ternary composite photocatalyst. The probable photocatalytic mechanism and the main active radicals for the degradation process were well defined with the help of elemental trapping experiment.

TiO2/g‐C3N4 hybrids (TCNs) were constructed by an ammonium salt‐assisted hydrothermal‐high temperature calcination method and used to activate peroxymonosulfate (PMS) to degrade multiple simulated pollutants. The Z‐scheme heterojunction between TiO2 and g‐C3N4 can effectively promote the separation of electron‐hole pairs and improve the photocatalytic activation effect of TCN. The degradation efficiency of RhB in the TCN1/PMS system was 92.3 %, which was only 59.8 % and 63.2 % in g‐C3N4 /PMS the g‐C3 N4/PMS system and TiO2/PMS system, respectively, after 60 min of reaction under sunlight. The TCN1‐4 sample prepared by adding (NH4)2SO4 into the precursor of TCN1 has a higher specific surface area (116.44 m2/g), which provides a better photocatalytic activation effect on PMS: the degradation efficiency of RhB in the TCN1‐4/PMS system can reach 93.9 % after 30 min, which was similar to that of the TCN1/PMS system after 60 min (92.3 %), and the reaction efficiency was doubled. Radical quenching experiments showed that free radicals (⋅OH, SO4⋅−, ⋅O2−), nonradicals (1O2) and h+ existed in the TCN1‐4/PMS reaction system.
