“…17,18 In photocatalytic technology, nano-scaled semiconductor materials have been widely used in recent years because of their low cost, easy synthesis, non-toxicity, and environmental friendliness. 19 Moreover, in the photocatalysis process, numerous essential aspects must be considered, including the band gap energy, effective surface area, light energy absorption characteristics, and optical properties of the photocatalytic materials 20 as well as the operation intensity, temperature, and pH of the photocatalytic degradation. 21 Semiconductor-based materials, such as ZnO, 23 NiO, 24 Fe 2 O 3 , 25 CuO, 26 CoFe 2 O 4 , 27 NiFe 2 O 4 , 28 and Cd-doped SiO 2 , 29 have been widely used in the photocatalytic degradation process.…”

Lanthanum oxide was successfully synthesized by hydrothermal method by varying the reaction time such as 6, 12, and 24 h. In XRD, study confirms the presence of a hexagonal structure, and the phase remains the same at different times; the main goal is to assess the average crystallite size of prepared La2O3 nanoparticles, which was found in the range of 6 to 8 nm. An interesting observation from the XRD data was the apparent increase in crystalline nature as the synthesis time was extended. The UV–Vis spectroscopic studies show a change in the band gap when the reaction time is changed. The morphology analysis shows that the image revealed that the particles formed were agglomerated and formed a spherical shape, with diameters ranging between 35 and 86 nm. When tested for photocatalytic activity, the La2O3 nanoparticles show a degradation of methylene blue dye when the time varies. Remarkably, the nanoparticles synthesized exhibited a profound ability to degrade the dye, with an efficiency rate hitting as high as 89% under halogen light illumination.

This study successfully synthesized ZnO–CuO nanocomposite using the hydrothermal method with Carica papaya leaf extract. The incorporation of the leaf extract significantly enhanced the nanocomposite properties, a novel approach in scientific research. Characterization techniques, including X-ray diffraction, Fourier Transmission Infrared spectroscopy, and Scanning Electron Microscopy with Energy Dispersive X-Ray Analysis, confirmed a cubic crystal structure with an average size of 22.37 nm. The Fourier Transmission Infrared spectrum revealed distinctive vibrations at 627, 661, and 751 cm−1 corresponding to ZnO–CuO nanocomposite corresponding to stretching and vibration modes. SEM images confirmed a cubic-like and irregular structure. The nanocomposite exhibited outstanding photocatalytic activity, degrading methylene blue dye by 96.73% within 120 min under visible light. Additionally, they showed significant antimicrobial activity, inhibiting Staphylococcus aureus (20 mm) and Klebsiella pneumonia (17 mm). The results highlight the efficiency of Carica papaya leaf-derived ZnO–CuO nanocomposite for environmental and health challenges. Graphical abstract
