HYDROTHERMAL SYNTHESIS OF FLOWER-SHAPED ZnSNANOCRYSTALS FOR NONENZYMATIC ELECTROCHEMICAL GLUCOSE DETECTION

In this letter, we reported a hydrothermal method for synthesizing flower-shaped ZnSnanocrystal using Zn(NO3)(2)center dot 6H(2)O and thioacetamide as precursors. The prepared flower-shaped ZnS was characterized by SEM, XRD, EDX and fluorescence spectrophotometer. The results indicate the proposed synthesis method could yield a high purity of flower-shaped ZnS with diameters of 110 nm. The application of these ZnSnanoflowersas electrochemical glucose sensor was successfully explored. Due to the high surface area and excellent electrocatalytic activity of the ZnSnanoflower, the constructed electrochemical sensor exhibited a high selectivity and a low detection limit. Moreover, the proposed glucose sensor also displayed excellent stability, reproducibility and anti-interference property.
