Electrochemical and Photocatalytic Properties of Biosynthesized Alkaline Earth Metal Doped Titanium Dioxide Nanoparticles

Abstract

Magnesium doped TiO₂ nanoparticles were effectively prepared using green synthesis approach. The synthesised Mg-TiO₂ nanoparticles are examined using XRD, UV-Vis, FTIR, EDX, electrochemical and Photocatalytic activity techniques. The structure, average crystalline size, dislocation density and microstrain were revealed by powder X-ray diffraction. The FTIR analysis indicates the presence of the vibrational modes of the Ti-O-Mg bond. The morphology of the sample was confirmed by SEM. The presence of Ti, O and Mg was analysed by the EDX spectrum.  The specific capacitance of the prepared sample was calculated at various scan rates by cyclic voltammetry. The percentage of degradation was analysed by the photocatalytic activity.
