 Abstract
10 wt.% and 20 wt.% composite powders are synthesized by a sol-gel method using titanium isopropoxide and as precursors. The as-received amorphous 10 wt.% composite powders crystallize into the anatase-type crystal structure upon calcination at , which then changes to the rutile phase at . The asreceived 20 wt% composite powders, on the other hand, crystallize into the anatase-type structure. As the calcination temperature increases, the anatase phase gets transformed to the phase. The peaks for the samples obtained after calcination at mainly exhibit the and phases. For a comparison of the photocatalytic activity, 10 wt.% and 20 wt.% composite powders calcined at , , and are used. The 20 wt.% composite powders calcined at show excellent efficiency for the removal of methylorange.
