Structural, Morphological and Dielectric Properties of Green Synthesised TiO₂ Nanoparticles for Energy Storage Applications

Titanium dioxide $\left(\mathrm{TiO}_{2}\right)$ nanoparticles are synthesized by green synthesis method using lemon juice as a fuel. The study aimed to address gaps in the exploration of dielectric properties of green-synthesized $\mathbf{T i O}_{2}$ nanoparticles. The prepared nanoparticles were subjected to different characterizations to understand their structural, morphological and electrical properties. X-ray diffraction (XRD) was used to analyze the structural and phase composition of the produced TiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>, while energy-dispersive X ray spectroscopy (EDX) was used to know the elemental composition and purity of sample, scanning electron microscopy (SEM) looks at the surface shape and texture and produces comprehensive images of the nanoparticle surfaces. The dielectric properties of TiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> nanoparticles such as dielectric constant, dielectric loss, impedance, and electric modulus are thoroughly studied as a function of frequency. The material’s dielectric characteristics is seen to be frequency-dependent, according to the study. The obtained results exhibit that prepared material can be used as promising anode material in batteries and super capacitor applications.
