摘要：
The factors that influence the photo-stability of Ag@AgBr plasmonic photocatalyst, such as light resource, electron/hole quencher, dye sensitizer, and atmosphere environment, were investigated in detail. It was revealed that Ag@AgBr can remain stable under weak light sources while it will become unstable under strong light sources. Electron quenchers are favorable to improving the stability of Ag@AgBr while hole quenchers do the opposite. Acting as a sensitizer, acid orange 7 dye is detrimental to the stability of Ag@AgBr. As for the atmospheric environment, air and oxygen-rich atmospheres are more favorable for keeping the stability of Ag@AgBr than vacuum atmosphere.
