Polyol-Mediated Synthesis of TiO₂ Nanoparticles

Abstract:

TiO2 nanoparticles were synthesized from a triethylene glycol solution of titanium isopropoxide (Ti(O-iPr)4) by refluxing at 270°C for 12 hrs. The as-prepared sample was heated at 600 °C for 3 hrs in order to study the thermal stability of the sample. The X-ray diffraction patterns of the samples were well indexed to the anatase phase. The field emission TEM images show uniform spherical morphologies with average sizes of 25 nm. The electrochemical measurements revealed that the discharge capacities of the heated sample exhibited high capacities and good rate performances without capacity fading during extended cycles, due to their electrochemically beneficial highly crystalline structures, nano-sized particles, and uniform distribution.
