In this work, we successfully prepared one dimensional (1D) AgBr@Ag nanostructures in high yield by a facile wet chemical method, and the plausible growth mechanism was discussed. The synthesis of as-prepared AgBr@Ag nanostructure is a dissolution and recrystallization process, and the PVP and DMSO have a synergistic and competitive effect on the preparation of 1D AgBr@Ag products. Moreover, the AgBr@Ag nanorods exhibit excellent photocatalytic activities under visible light illumination, which may be attributed to their large surface area as well as superior charge separation and transfer efficiency compared to AgBr@Ag particles.
