Barium titanate nano particles have been prepared by
co-precipitation in aqueous solution followed by calcination.
The samples were analyzed using a series of techniques including
XRD and TG. The particle size was calculated based on the
Scherer equation and the average particle size vary from 50 to
80 nm. The photocatalytic activity was evaluated in the
degradation of methyl orange in aqueous solution. The results
show that BaTiO3 nano particles exhibit good
photocatalytic activity under visible range condition.
KEY WORDS: Barium
titanate, Photocatalyst, Co-precipitation.
