Abstract Due to characteristic properties of silver (Ag), Ag nanoparticles have attracted unprecedented attention in various scientific fields such as sensors, catalysts, antibacterial materials, and so on. To obtain tailor-made functionalities of Ag nanoparticles with desired physicochemical properties, proper fabrication process is needed to control their sizes, morphologies or arrangements by hybridization with different components, immobilization on solid struts, and etc. Herein, we suggest a facile synthetic route to obtain Ag-pillared mesoporous nanoclays through simultaneous crystal growth and arrangement of Ag nanoplates with the help of a 2-dimensional inorganic template. To obtain Ag-pillars, layered silver-thiolate self-assembly was exfoliated to monolayers (Ag precursor) and then in-situ hybridized with layered double hydroxide in a layer-by-layer manner. Through reductive calcination, silver thiolate transformed to Ag-pillars which grew in nanoplate morphology with well-arrangement in confined space of nanoclays. Crystal structure, morphology, and pore structure of Ag-pillars in nanoclays were systematically characterized. Surface enhanced Raman scattering effect of arranged Ag-pillars on metal oxide substrate obtained upon calcination was also investigated with rhodamine 6 G.

用于表面增强拉曼散射的银纳米板柱状介孔纳米粘土

摘要 由于银（Ag）的特性，银纳米粒子在传感器、催化剂、抗菌材料等各个科学领域引起了前所未有的关注。为了获得具有所需物理化学性质的 Ag 纳米粒子的定制功能，需要通过与不同组分杂交、固定在固体支柱上等方式来控制它们的尺寸、形态或排列。在此，我们提出了一种简便的合成路线在二维无机模板的帮助下，通过同时晶体生长和银纳米片的排列，获得银柱撑介孔纳米粘土。为了获得银柱，层状硫醇银自组装被剥离成单层（Ag 前体），然后与层状双氢氧化物以逐层方式原位杂交。通过还原煅烧，硫醇银转化为银柱，银柱在纳米粘土的密闭空间中以纳米片形态生长，排列良好。系统地表征了纳米粘土中银柱的晶体结构、形态和孔结构。还使用罗丹明 6 G 研究了排列的 Ag 柱在煅烧后获得的金属氧化物基材上的表面增强拉曼散射效应。并系统地表征了纳米粘土中银柱的孔结构。还使用罗丹明 6 G 研究了排列的 Ag 柱在煅烧后获得的金属氧化物基材上的表面增强拉曼散射效应。并系统地表征了纳米粘土中银柱的孔结构。还使用罗丹明 6 G 研究了排列的 Ag 柱在煅烧后获得的金属氧化物基材上的表面增强拉曼散射效应。
