Because of the aggregation of small Li particles into bigger bulk Li particles during the doping process, the addition of Li dopant has a slightly negative influence on the ZNF surface area.…”

Conventional methods are inefficient to treat water contaminated with persistent organic contaminants. To decontaminate bacteria and 2,4,5‐trichlorophenol (TCP) contaminated water, a heterogeneous photocatalysis‐based advanced oxidation process was applied in this study. A Li‐doped ternary Zn0.5Ni0.5Fe2O4 (ZNF) photocatalyst (Li/ZNF) was synthesized via a facile co‐precipitation technique and characterized. The Li/ZNF has a sufficient specific surface area (69.8 m2.g−1), and an appropriate bandgap of 2.89 eV. Under optimal conditions, 10 mg of Li/ZNF photocatalyst degraded 80 % of 50 mg L−1 TCP in 6 h at pH 3 in the presence of 4 mM H2O2. After use, the Li/ZNF photocatalyst was magnetically separated and reused numerous times, with an efficiency of 66 % after the fifth reuse cycle. In the antibacterial time‐kill assay, 15 and 25 mg of Li/ZNF inhibited 1×107 CFU.mL−1 of S. Aureus and E. coli bacteria after 60 min of UV exposure, respectively.

“…Phenolic compounds are discharged to ecology through effluent from many industries for instance, paint production, processing of petroleum, tanning, and pharmaceuticals. [40][41][42] The conventional treatment is not very effective for the removal of these hazardous pollutants. Thus, the development of novel techniques is essential to address this issue.…”

“…Owing to its unique optical and electrical characteristics and with average estimations ranging from 4.0 to 7.0 eV, based on this range of ZrO 2 , with a band gap relatively less. Furthermore, fabrication procedures are also used because of the synthesized nanomaterials' more excellent crystallinity, controlled morphology, and ne particle size distribution [16,17]. In recent years, various strategies, like metal doping, metal oxides, and proper backings, such as diminished graphene oxide, were employed to adjust the band gap energy of ZrO 2 and advance its apparent light photocatalytic movement [1,2,[18][19][20].…”

Phenolic compounds are present as a recalcitrant chemical in the effluents of industrial wastewater. They are highly carcinogenic and need proper treatment for their degradation to prevent human health. Even though conventional methods are available for degrading the phenolic compounds in the aqueous medium, they are not effective and are associated with high costs. Thus, in the current work, we deal with the degradation of O-Nitrophenol by using ZrO2 nanoparticles and ZrO2-RGO nanocomposite produced by a hydrothermal process with a lower cost under the visible light photolytic activity. The ZrO2-RGO nanocomposite outperformed the ZrO2 nanoparticles with higher degradation efficiencies. Though many researchers attempted to reduce the phenolic compound in the waste-water, according to the available literature, we have achieved the highest removal efficiencies, i.e., 98.4% in removing O-Nitrophenol. The morphology of the ZrO2-RGO nanocomposite was using BET, SEM-EDX, XRD, FT-IR, and UV-DRS analysis. XRD patterns revealed that the ZrO2 is highly crystalline, which might be attributed to the higher degradation. SEM pictures show that ZrO2 particles exhibit a limited size distribution and a consistent needle-like nanostructure. Through synthesis, FT-IR patterns showed the graphene oxide (GO) with reduced graphene oxide (RGO). The improved visible light degrading activity of ZrO2-RGO NC supported the UV-vis DRS. Thus, from the results, we conclude that ZrO2-RGO NC in the photodegradation of O-Nitrophenol, when illuminated with visible light, might be the best solution for the degradation of the phenolic compound.
