Abstract
The main focus of this work is to choose a stabilizer which plays a significant role in enhancing the conductivity of Co@TiO2 nanoparticles. Poly Vinyl Pyrrolidone (PVP) and zeroth generation triazolyl Glycodendrimer were the stabilizing agents whose activity on Co@TiO2 nanoparticles has been compared. As a semiconductor with extreme resistivity Co@TiO2 shows good conductivity due to the presence of cobalt at the core which was further improved by suitable stabilizing agent. Being less reactive when exposed to light, glycodendrimer lags behind PVP in the conductivity test results. The results obtained from impedance analysis, UV–Diffuse Reflectance Spectrograph and photoconductivity shows that the activity of PVP stabilizer is better than glycodendrimer. The structural analysis of the synthesized samples shows that the lattice strain experienced by PVP is less than that of glycodendrimer.
