Preparation and characterization of phase-pure anatase nanoparticles

Abstract EN

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.
