Enhancing the electrical, optical, and structure morphology using Pr2O3-ZnO nanocomposites: Towards electronic varistors and environmental photocatalytic activity

• The combustion as a simple, inexpensive, and environmental method was used to prepare the samples of undoped several concentrations praseodymium-doped zinc oxide (Pr 2 O 3 -ZnO) nanoparticles. morphological structure investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FT-IR) prepared Pr -ZnO photocatalysts. UV–Vis diffused reflectance (DR), AC electrical conductivity studied investigate 3+ -nanoparticles' influence on optical characteristics, energy bandgaps, all proposed nanostructured samples. addition dopants decreases bandgap slightly confines photogenerated electron-hole recombination. nano-samples have been applied in photocatalytic degradation methylene blue (MB) p-chlorophenol (p-CP) under visible light irradiation. -concentration, H concentration, pH medium reaction studied. As praseodymium doping ratios increased; efficiency increased. After moderate -doping, further generation hydroxyl radicals over ZnO. For 1% -ZnO, optimal photocatalyst is 100% solutions. nanostructures are promising candidates potential nano-applications for wide-ranged from varistors, wastewater treatments, biomedical different fields. In this research, - ZnO) nanoparticles ranged 0.001 g 5 were synthesized using technique efficient, method. structure, morphology, chemical bonding respectively, attained data previous devices sustained ZnO growth crystalline satisfactory nanoparticle through changing -doping inside host matrix. Furthermore, features via an example organic dyes amazing, novel phenol
