Synthesis of AgBr/Bi₂WO₆ Heterojunction with Enhanced Photocatalytic Activities for Methyl Orange

Abstract:

AgBr nanoparticle decorated mesoporous Bi₂WO₆ architectures was fabricated via a facile precipitation-deposition process. As-prepared AgBr/Bi₂WO₆ heterojunction was characterized by XRD, FE-SEM and HR-TEM. The photocatalytic activities of the samples were evaluated by the photodegradation of methyl orange (MO) under visible light irradiation. The results showed that AgBr nanoparticles decrodation great improved the photocatalytic activity of Bi₂WO₆. The 2.0at%AgBr/Bi₂WO₆ sample exhibited the best photocatalytic activity for decolorization of MO.Furthermore, the mechanism of enhanced photocatalytic activity for hierarchical AgBr/Bi₂WO₆ heterojunction was also discussed.
