摘要
Recently, spinel ferrites have attracted great attention as a SERS-active substrate for the detection of organic contaminants. In this paper, we report the synthesis of silver enriched MOF-derived CuFe2O4 (Ag-CFO) composite using a simple MOF template process. The as-synthesized Ag-CFO exhibits an excellent sensitivity towards the detection of Rhodamine 6G dye at the lowest concentration of 10-14 M. Using noble metal nanoparticles in conjunction with CuFe2O4 provides an excellent SERS performance based on the synergistic effect resulting from uniform Ag distribution on the cubic morphology leading to the high electromagnetic effect and chemical mechanism of CuFe2O4. Ag-CFO microcubes also demonstrated remarkable recyclability, reproducibility, and chemical stability. Moreover, the substrate showed good sensitivity when it was examined in tap and river water for practical applications. The results confirm that Ag-CFO microcubes substrate has great potential as a reusable material for the rapid detection of environmental pollutants.
