Abstract Developing stable and highly efficient metal oxide photocatalysts remains a significant challenge in managing organic pollutants. In this study, zinc nanoparticles (ZnO NPs) were successfully synthesized using various plant extracts, pomegranate (P.M), beetroot roots (B.S), seder, along with chemical process. The produced ZnO NPs characterized X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), ultraviolet–visible (UV–Vis), Field Emission Scanning Electron Microscope (FESEM), High-Resolution Transmission Microscopy (HRTEM), Surface Area. For all prepared samples, the results indicated that composition of extract affects several characteristics particles, such as their photocatalytic properties, energy bandgap (E g ), particle size, ratio two intensity (0 0 2) (1 0) crystalline planes. size varies between 20 30 nm. To examine NPs' activity presence UV light, Methyl Orange (MO) was utilized. E by method 3.16 e. V, whereas it 2.84, 2.63, 2.59 for P.M, Seder, B.S respectively. most effective NPs, Beetroots, exhibited degradation efficiency 87 ± 0.5% kinetic rate constant 0.007 min −1 . planes also examined to determine specific orientation is linked production oxygen vacancies ZnO, which enhances efficiency. Furthermore, increase effectiveness can be attributed improved light absorption inter-band gap states charge transfer.

The ability of photocatalysis to clean up environmental contamination, notably in the treatment water and air, has received extensive research. composite materials synthesized by coprecipitation method were made ZnO graphitic carbon nitride (g-C3N4) with various concentrations lanthanum doping (La-ZnO). It was discovered that La metal ions evenly distributed throughout layered stacking structures nanosheet, which had an impact on band structure increased rate electron-hole separation visible light absorption. First-principles calculations show La-doped ZnO-gC3N4 possesses a direct gap type-II conduction minimum valence maximum located separate layers. A built-in electric field from gC3N4 been established through analysis charge density difference, Bader charge, work function, alignment. pair becomes spatially separated as result, increases photodegradation activity. High interfacial transfer, efficient migration, high optical absorbance caused coating ultra-thin g-C3N4 layer. 0.6 % degraded 97 bromothymol blue (BB) dye, four times higher than bulk ZnO, could remove only about 21 dye at same time. combined effects lower photo corrosion, solar usage owing hollow heterostructured semiconductor contribute this photocatalytic capacity ZnO/g-C3N4 nanocomposite effectively break down BB via suggests it potential address problems associated pollution systems.

A series of simple and low-cost Ca-doped g-C3N4 (Ca/CN-X) photocatalysts were fabricated through a two-step calcination method for photodegradation methylene blue (MB) simulated dyeing wastewater. The results showed that the efficiency Ca/CN-15 % on MB removal under visible light was 97.7 %, degradation rate constant 4 times CN, showing best photocatalytic performance. This attributed to fact doping Ca expanded absorption band edge, reduced gap, suppressed photogenerated electron-hole recombination, thereby increasing its corresponding activity. possible mechanism explored, it found h+ main active species during process. above indicated Ca/CN-X can be regarded as promising catalyst wastewater treatment.
