Controlled Growth of Silver Nanowires with Chemically Exfoliated Ti₃C₂T_x Nanosheets

Silver nanowires(Ag NWs) are important materials for next-generation transparent conductors(TCs). However, Ag NWs synthesized by polyol reduction have large diameters, which affects the optical and electrical properties of Ag NWs thin films. Herein, we propose a new method for the synthesis of Ag NWs using MXene, and the growth of Ag NWs with different diameters can be achieved by controlling the size of nanosheets. The growth mechanism was studied by high-resolution transmission electron microscopy(HRTEM), revealing the important role of MXene as both a reducing and nucleating agent. Therefore, our work exhibits that as a novel two-dimensional layered material, MXene is helpful for the synthesis of high-quality Ag NWs, making them a new-generation material for high-performance flexible transparent electrode.
