Synthesis and Characterizations of Co-Doped TiO2 Nanoparticles Via Co-Precipitation Method
Abstract
Titanium dioxide (TiO2) nanoparticles (NPs) are playing an important role in electronic appliances. In the current study, a co-precipitation method was used to prepare Cobalt doped TiO2 nanoparticles at various Cobalt percentages (4%, 5%, 6%, and 7% w/w). Titanium tetra isopropoxide (TTIP) and cobalt nitrate were used as starting precursors for titanium dioxide and Co nanoparticles, respectively. The gained products were calcined at 500°C to observe three phases (anatase, brookite, and rutile) of TiO2. The analysis of crystal phase structure, average crystallite size, hkl planes, the lattice constant, and volume of the unit cell of Cobalt doped TiO2 nanoparticles (NPs) was carried under X-ray diffraction (XRD). The structural, optical, and morphological characterizations of the samples were analyzed by X-Ray Diffraction XRD (XRD), Ultraviolet-visible (UV-vis) spectroscopy, and scanning electron microscopy (SEM), respectively. It was observed that the XRD patterns contain the peaks belonging to anatase, brookite, and rutile phases of TiO2. The optical characteristics, including the absorption spectra of the prepared specimens, were investigated using UV-Vis spectroscopy, while SEM confirmed the observation of composition changes in samples with a higher concentration of cobalt. The UV-vis spectroscopy revealed that the energy band gap decreases as the Co content of the NPs increases. The SEM images indicated that the particle size slightly changes with the Co content. The functional groups of cobalt doped TiO2 nanoparticles were assured by Fourier transform infrared spectroscopy (FTIR). These findings indicate the possibility of tuning optical and structural properties of Cobalt doped TiO2 through doping with various concentrations of Co nanoparticles and has the potential to find application in optoelectronic device application.
