R
ecently, 2D layered transition metal dichalcogenide materials have received great consideration because of their
unique electronic properties, large surface area and high electrocatalytic activity. In this connection, for the first time
the similar nanostructured material of NiSe
2
nanosheets (NiSe
2
-NS) has been synthesized by a facile hydrothermal method
for electrocatalytic applications. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray
photoelectron spectroscopy (XPS), energy dispersive x-ray analysis (EDX) and x-ray diffraction spectrum (XRD) results
confirmed the formation of NiSe
2
-NS with required stoichiometry and morphology. Electrochemical impedance spectroscopy
(EIS) data indicate that electron transfer is facile at the NiSe
2
-NS modified glassy carbon electrode (GCE). It has been an
electrode modifier for glucose sensing applications. The electrochemical studies were performed for NiSe
2
-NS modified GCE
using cyclic voltammetry (CV) and Amperometric i-t techniques. The results are suggesting the effective response of NiSe
2
-
NS/GCE with a very low limit of detection (LOD) and sensitivity of 23 nM and 5.6 µA µM-1cm
-2
respectively. Moreover, the
selectivity data exhibited excellent anti-interference property of NiSe
2
-NS/GCE towards glucose in the presence of possible
interfering agents viz. ascorbic acid, dopamine, and glucose.
