In this study, we have adeptly fabricated a unique tri-phasic nanocomposite incorporating MgO, CuO, and Cu2MgO3 via meticulous sol–gel technique. The comprehensive characterization of the material was conducted using suite analytical methods including Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–visible spectroscopy. XRD patterns confirmed coexistence MgO's cubic crystallinity, CuO's monoclinic lattice, Cu2MgO3′s orthorhombic structure within synthesized composite. Utilizing Scherrer equation, crystallite dimensions were determined to range between 31 70 nm. spectral analysis pointed bandgap energy 4.26 eV for nanocomposite, suggesting its suitability optoelectronic applications. material's antimicrobial potency also evaluated, showcasing notable inhibitory action against both Gram-positive bacteria, with zone inhibition (ZIO) measuring 18 mm at highest concentration, Gram-negative E.coli which displayed an 11 ZIO similar concentrations. amalgamated results underscore MgO-CuO-Cu2MgO3 nanocomposite's potential as multifunctional advancing technologies promising antibacterial capabilities.

Background: Ca aluminate (CaAlO) is an important material that shows promising applications in optics, catalysts, photoelectrons, semiconductors, and biological materials. The band gap of the CaAlO nanoflakes as large 3.87 eV, limiting application nanoflakes. Thus, it essential to research efficient methods for improving photocatalytic performance improvement gentian violet degradation can be further enhanced by lanthanide metal doping. Methods: Lanthanide (La or Pr)-doped were prepared using a simple method. metal-doped analyzed electron microscopy, X-ray diffraction, photoelectron spectra, solid diffusion reflectance, photoluminescence spectra. Results: La Pr was incorporated into with orthorhombic Ca5Al6O14 phase. dopant content 8wt.% existed form hexagonal La0.9Al11.7O19. induced phase transformation from cubic Ca3Al2O6 size doped reduced 2 μm 500 nm increasing dopants. decreased 3.74 eV 2.98 decreasing 8 wt.% wt.%, 3.62 3.34 wt.%. About 20 mL 10 mgL-1 entirely removed wt.%-La-doped under irradiation 30 min, 8wt.%-Prdoped 50 respectively. 2wt.%-La-doped exhibited highest reaction rate constant (0.115 min-1), which 3.6 times high major active substances involved photo-degradation hydroxyl radicals holes. Conclusion: Photocatalytic activity towards greatly metals owing harvest light absorption, gap, recombination ability photo-generated electron-hole pairs.
