Abstract
Bismuth oxide (Bi 2 O 3 ) is a well-studied photocatalyst for degradation of various environmental contaminants. In this research Bi 2 O 3 has been synthesized by precipitation method using two different bases (NH 4 OH and NaOH). The samples thus obtained were then analyzed using FTIR, XRD, and SEM for surface functionalization, crystal structures and morphological differences, respectively. The Bi 2 O 3 precipitated using NH 4 OH showed a flower like structure made up of individual plates having α-Bi 2 O 3 crystal structure. The precipitate obtained using NaOH showed a honeycomb like flower structure with a mixture of both α-Bi 2 O 3 and γ-Bi 2 O 3 crystal structure. Degradation of methyl orange (MO) was used as a model system to test the photocatalytic activity of the bismuth oxide. The Bi 2 O 3 synthesized using NH 4 OH showed superior photocatalytic degradation of methyl orange than the one synthesized using NaOH. Copyright © 2017 BCREC Group.
