| Abstract | ||
| The anatase phase of titania has great potential to be used in various applications. Thus; the synthesis of phase-pure nanocrystalline anatase has attained great importance in the past decade. In the present work, the sol-gel method was used to prepare such nanoparticles. It has been found that the sol-gel method can, with the help of long aging time, produce phase-pure anatase nanoparticles that have polygonal shape with edges’ length in the range of (~30-70nm). The firing temperature should be kept higher than 500°C to get fully crystalline nanoparticles and lower than 800°C to avoid the phase transformation to rutile phase | ||
