Abstract
Present investigation describes a successful preparation of nickel phosphate (Ni3(PO4)2.8H2O) thin film electrodes by facile one pot hydrothermal method. As developed Ni3(PO4)2.8H2O thin film electrodes with the variation of thickness are examined for morphological change and glucose sensing. The Ni3(PO4)2.8H2O thin film electrodes exhibit linear response with respect to the variation in glucose concentration from 2.5 to 30 mM and acquire the sensitivity of 8312 μA mM−1 cm−2 with 437 μM LOD. Selectivity performance of Ni3(PO4)2.8H2O thin film electrode towards glucose in presence of dopamine, fructose and lactose is studied. The results suggest that Ni3(PO4)2.8H2O thin film electrode is beneficial for glucose sensing application due to enormous active sites with the high specific surface area of the active material.
