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.
