摘　　要：通过阳极氧化结合氨气还原氮化法制备出TiN纳米管,利用电化学沉积在其表面沉积Ag纳米粒子,最后原位生长ZIF保护壳层制备出ZIF@Ag-TiN复合基底,借助XRD、SEM、Raman等测试手段对该复合基底进行测试与表征,结果表明所制备的复合基底中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ZIF纳米粒子,可赋予复合基底更好的抗氧化保护性能,同时复合基底的SERS性能也得到了提升,其对R6G的检测限可达到10^(-12)M。TiN nanotubes were prepared by anodic oxidation combined with ammonia reduction and nitridation,and Ag nanoparticles were deposited on the surface by electrochemical deposition.Finally,ZIF protective shell was grown in situ to prepare ZIF@Ag-TiN composite substrate.XRD,SEM and Raman were used to measure the composite substrate.And the results showed that the TiN nanotube array structure of the prepared composite substrate was uniform and complete,silver nanoparticles were evenly distributed on the surface of the array structure,and the surface of the substrate was coated with ZIF nanoparticles with regular shape,which could give the composite substrate better antioxidant protection performance,and the SERS property of the composite substrate was also improved.The detection limit of R6G can reach 10^(-12)M.
