摘要
Abstract In this paper, ZnCo 2 S 4 nanomaterial with a unique structure were synthesized by static and hydrothermal method and applied to the field of electrochemical sensing. Based on the advantages of metal-organic frameworks (MOF) materials with large specific surface areas, multiple active centers, and synergistic effect of multi-metals, we choose Zn and Co bimetallic MOF as the precursor material and synthesized ZnCo 2 S 4 nanomaterials with large active area and multiple active centers after vulcanization. In addition, we verified the excellent electrochemical sensing performance of the prepared ZnCo 2 S 4 nanomaterial through the catalytic oxidation experiment of glucose. The results showed that ZnCo 2 S 4 nanomaterials with bimetallic MOF as a precursor had higher electrocatalytic activity for glucose oxidation than ZnCo 2 S 4 nanomaterials without precursor and single metal sulfide. According to the analysis of the electrochemical performance of the material, the detection limit is extremely low (0.007 μ M)and two linear range (3 ∼9 μ M) and (10 ∼100 μ M)for glucose. Therefore, we believe that the method of preparing polymetallic sulfides with MOF as a precursor is of great significance in electrochemical sensing.
