本文采用湿化学方法成功地制备了一维AgBr@Ag纳米结构，并对其生长机理进行了探讨。所得AgBr@Ag纳米结构的合成是一个溶解和重结晶过程，PVP和DMSO对一维AgBr@Ag产物的制备具有协同和竞争作用。此外，AgBr@Ag纳米棒在可见光照射下表现出优异的光催化活性，这可能归因于其大的表面积以及与AgBr@Ag颗粒相比优越的上级电荷分离和转移效率。
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.
