摘要
通过阳极氧化结合氨气还原氮化法制备了氮化钛纳米管阵列结构,再利用电化学沉积技术结合原位生长法制备出MOF@Ag-TiN复合SERS基底。结果表明,所制备的MOF@Ag-TiN复合基底存在面心立方晶型TiN、银单质和钴基MOF三种物相,通过扫面电镜技术发现TiN纳米管阵列结构均匀完整,银纳米粒子均匀分布在阵列结构表面,同时基底表面包覆有形状规则的MOF纳米粒子。MOF@Ag-TiN复合基底具有较好的拉曼增强性能,对探针分子R6G的检测限为10^(-12)M,同时还具有良好的稳定性。
Titanium nitride nanotube array structure was prepared by anodic oxidation combined with ammonia reduction nitriding method,and MOF@Ag-TiN composite SERS base was prepared by electrochemical deposition technology combined with in situ growth method.The results show that MOF@Ag-TiN composite substrate had three phases:face-centered cubic crystalline TiN,silver elemental and cobalt-based MOF.By scanning electron microscopy,it was found that the TiN nanotube array structure was uniform and complete,silver nanoparticles were uniformly distributed on the surface of the array structure,and the substrate surface was coated with MOF nanoparticles with regular shape.MOF@Ag-TiN composite substrate had good Raman enhancement performance,the detection limit of probe molecule R6G was 10^(-12)M,and also had good stability.
