Preparation method of Fe-CoP nano material and application of Fe-CoP nano material in electrochemical detection
The invention discloses a Fe-CoP nano material, a preparation method and application in electrochemical detection. The preparation method comprises the following steps: dissolving cobalt nitrate hexahydrate, ferrocene and CTAB (Cetyltrimethyl Ammonium Bromide) in absolute methanol, and uniformly stirring to form a solution A; dissolving dimethylimidazole in absolute methanol, uniformly stirring to form a solution B, quickly adding the solution A, stirring, reacting, washing, drying to obtain Fe (C5H5) 2 (at) ZIF67, and calcining to obtain intermediate powder Fe-Co3O4; naH2PO2 is placed on the upstream portion of a tubular furnace, the intermediate powder Fe-Co3O4 is placed on the downstream portion of the tubular furnace, calcination is conducted in the protective gas atmosphere, and the Fe-CoP nanometer material is obtained. The Fe-CoP nano material is coated on the surface of a GCE electrode to form a working electrode, the working electrode can be used for metal detection in an actual water sample in a three-electrode system, the limit of detection (LOD) of Cd (II) is 0.01 mu M, and the sensitivity and the selectivity are high..
