Herein, on the titanium oxide coated copper sheet, Ag nanoparticles were grown with cobalt 2-methylimidazole metal–organic framework (ZIF-67) as a special medium. Subsequently, a novel sheet with sandwich structure (Ag/ZIF-67/Ag-TiO₂/Cu, abbreviated as AZATC) was constructed. By X-ray powder diffraction, electron microscopies, and X-ray photoelectron spectroscopy, the AZATC sheet were characterized. Compared to the Ag/ZIF-67/TiO₂/Cu (AZTC) composite and some traditional substrates, the AZATC with sandwich Ag showed a more sensitive enhanced surface enhanced Raman scattering (SERS) response to phenol red (PhR, 1 × 10^-10 M). Furthermore, the plug and play AZATC sheet showed excellent and stable photocatalytic degradation for PhR even if it was recycled for 6 times. Especially, the novel and cost-effective AZATC was also used to efficiently detect and degrade the PhR in real samples.

在此，在氧化钛涂层的铜板上，以钴 2-甲基咪唑金属-有机骨架 (ZIF-67) 作为特殊介质生长了 Ag 纳米颗粒。随后，构建了一种具有夹层结构的新型片材（Ag/ZIF-67/Ag-TiO ₂ /Cu，简称AZATC）。通过 X 射线粉末衍射、电子显微镜和 X 射线光电子能谱对 AZATC 片材进行了表征。与Ag/ZIF-67/TiO ₂ /Cu (AZTC)复合材料和一些传统基板相比，夹层Ag的AZATC对酚红（ PhR，1×10 ^{- 10}米）。此外，即插即用的 AZATC 片材即使循环使用 6 次，也表现出优异且稳定的 PhR 光催化降解。特别是，新颖且具有成本效益的 AZATC 还用于有效检测和降解实际样品中的 PhR。
