Abstract Silver chain-like nanobelts (NBs) have been prepared by a redox-active ionic liquid (RAIL)|water (W) interfacial method with utilizing the soft interface as a template. A highly hydrophobic RAIL (ferrocenylmethyl)dodecyldimethylammonium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate ([FcMDDA+][TFPB−]) works as both the reducing agent and the liquid substrate in the RAIL|W interfacial system. The morphology of Ag chain-like NBs, which possesses flat surfaces, sharp corners on the edges, and large aspect ratio, combines the features of one-dimensional (1D) and 2D nanostructures. The formation of Ag chain-like NBs is realized by the linkage of small nanounits through an oriented growth along the RAIL|W interface. The size and shape of the Ag deposited at the RAIL|W interface can be controlled by regulating the concentration of Ag precursor in W, where higher (lower) concentration of AgNO3 induces the formation of Ag NBs with smaller (larger) size. The prepared Ag chain-like NBs show good surface enhanced-Raman scattering activity which can be used as the substrate for plasmonic applications.

在水和氧化还原活性离子液体之间的液-液界面处界面模板合成单晶银链状纳米带

摘要 以软界面为模板，通过氧化还原活性离子液体（RAIL）|水（W）界面法制备了银链状纳米带（NBs）。高度疏水的 RAIL（二茂铁基甲基）十二烷基二甲基铵四[3,5-双（三氟甲基）苯基]硼酸盐（[FcMDDA+][TFPB-]）在 RAIL|W 界面系统中既是还原剂又是液体底物。具有平坦表面、边缘尖角和大纵横比的银链状 NBs 的形态结合了一维 (1D) 和二维纳米结构的特征。Ag 链状 NB 的形成是通过沿 RAIL|W 界面的定向生长连接小纳米单元来实现的。沉积在 RAIL|W 界面上的 Ag 的尺寸和形状可以通过调节 W 中 Ag 前体的浓度来控制，其中较高（较低）浓度的 AgNO3 会诱导形成较小（较大）尺寸的 Ag NB。制备的银链状 NBs 显示出良好的表面增强拉曼散射活性，可用作等离子体应用的基材。
