Fabrication of binary (ZnO)x(TiO2)1-xnanoparticles via thermal treatment route and evaluating the impact of various molar concentrations on the structure and optical behaviors

Numerous studies have explored the behaviors of ZnO-TiO(2)nanoparticles resulting through various routes of fabrication. To date, the utilization of thermal treatment method to convey ZnO-TiO(2)nanoparticles has never been considered. In the present study, binary (ZnO)(x)(TiO2)(1-x)NPs were effectively blended by using thermal treatment technique. Zinc nitrate and titanium(IV) propoxide with polyvinylpyrrolidone, PVP, were utilized to set up the samples. Energy-dispersive X-ray (EDX) spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction (XRD) spectroscopy, ultraviolet-visible (UV-Vis) spectrophotometer transmission electron microscopy (TEM) and photoluminescence spectroscopy were utilized to examine the impact of changing the molar proportion to the structure and optical features of (ZnO)(x)(TiO2)(1-x)NPs. The XRD spectra revealed that after calcination, the amorphous sample had transformed into crystalline nanoparticles. The prepared (ZnO)(x)(TiO2)(1-x)NPs average diameter was around 25.922-28.531 nm according to TEM analysis. The analyzation of UV-Vis spectroscopy determined the optical measurements parameters including the energy gap and Urbach energy of binary (ZnO)(x)(TiO2)(1-x) NPs. The optical energy gap varied in the range of 3.2496-3.2863 eV as the molar ratio increases fromx = 0.24 tox = 0.72. The enhancement within the nanoparticles optical properties suggests a good potential for photocatalysis application.
