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.
