The materials were also tested for some potential chemical applications. We obtained pure single phased NiO materials as characterized by X-ray. Pure NiO showed cubic crystalline structure. Morphology was analyzed by SEM revealed oval/ spherical crystallites of Fe doped NiO samples where concentration was much low i.e. 2%. When dopant concentration was increased (4, 6, 8%) the materials showed unsymmetrical morphology. Doped NiO material (8%) was utilized to modify glassy carbon electrode for electrochemical sensing of various chemical analytes. Results show that as-synthesized this material exhibits good sensing response toward urea (CH₄N₂O) detection with high selectivity and sensitivity as compared to different interfering compounds.enThesis
