文摘

Ag@AgBr nanospheres have been synthesized through a simple method. X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electronmicroscopy, photoluminescence spectroscopy, X-ray photoelectron spectroscopy and UV–Vis diffuse reflectance spectroscopy, were used to characterize the as-synthesized nanospheres. The as-prepared Ag@AgBr photocatalyst can be used to remove the pollutants under direct sunlight. The as-prepared Ag@AgBr nanospheres show excellent visible-light photocatalytic performance and good reusability for decomposing organic pollutant of Rhodamine B and methyl blue due to the surface plasmon resonance effect of Ag and AgBr nanoparticles. Additionally, the recycling experiment of Ag@AgBr nanospheres has been done, demonstrating that Ag@AgBr nanospheres have high efficiency and stability.
