Mechanism Understanding for Size Regulation of Silver Nanowires Mediated by Halogen Ions.

ABSTRACT: The controllable preparation of silver nanowires (AgNWs) with a high aspect ratio is key for enabling their applications on a large scale. Herein, the aspect ratio regulation of AgNWs mediated by halogen ion composition in ethylene glycol system was systematically investigated and the size evolution mechanism is elaborately understood. The co-addition of Br^- and Cl^- results in AgNWs with the highest aspect ratio of 1031. The surface physicochemical analysis of AgNWs and the density functional theory calculations indicate that the co-addition of Br^- and Cl^- contributes to the much-enhanced preferential growth of the Ag(111) crystal plane. At the same time, when Cl^- and Br^- coexist in the solution, the growth of the Ag(100) cr
