A plasmonic Ag–AgBr/Bi2O2CO3 composite photocatalyst was prepared
by a two-step synthesis method.
The as-prepared Ag–AgBr/Bi2O2CO3 was characterized by X-ray diffraction, scanning electron microscopy,
transmission electron microscopy, and energy-dispersive X-ray, X-ray
photoelectron, ultraviolet–visible diffuse reflection, and
photoluminescence spectroscopy. As probe pollutants, rhodamine B (RhB)
and methylene blue (MB) were adopted to investigate the photocatalytic
activity of the Ag–AgBr/Bi2O2CO3 composite photocatalyst under visible light irradiation. The as-prepared
photocatalyst showed an enhanced photocatalytic activity for the degradation
of RhB and MB under visible light, which was attributed to the heterostructured
Ag–AgBr/Bi2O2CO3 and surface
plasmon resonance (SPR) exhibited by Ag nanoparticles. Simultaneously,
high stability of the sample was also investigated by five successive
photodegradations of RhB under visible light. The relationship between
photocatalytic activity and the structure of Ag–AgBr/Bi2O2CO3 is discussed, and possible reaction
mechanisms are also proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
