| Sumario: | This study is devoted to the synthesis of iron-doped nickel oxide nanomaterials with the help of the hydrothermal technique, to study the effect of different dopant concentrations on the structural, morphological, and Direct current properties. Various testing has been performed on the materials for their utilization in some potential chemical applications. X-ray study showed that the material is pure single phased NiO. A cubic crystalline structure was shown by pure NiO Morphology and was analyzed by SEM revealed oval/spherical crystallites of Fe-doped NiO samples where concentration was much low i.e., 2%. The materials showed unsymmetrical morphology when dopant concentration was increased (4% to 8%). Doped NiO material (8%) was utilized to modify the glassy carbon electrode (GCE) for electrochemical sensing of various chemical analytes. The results show that as-synthesized material exhibits a good sensing response towards urea (CH4N2O) detection with high selectivity and sensitivity as compared to different interfering compounds. |
