| Abstract: | Selective and highly sensitive detection of nitrite is always a challenge for electrochemist for the dministration of nitrite in water and food samples. In this regard nanostructured materials are crown choice. In the present investigation, we have prepared uniformly ordered hybrid Mn3+/4+ : ZrO2 nanoganitrus via ydrothermal method, characterized by XRD, BET, SEM, TEM and XPS to understand the structural and morphological features of the material and used for the electrocatalytic determination of nitrite. The preparation process resulted in the formation of nanoganitrus heterostructures with honeycomb arrangement. High surface area, ganitrus structure and hybrid Mn3+/4+ in the material was correlated to its robust electrochemical performance. Thus, prepared sensor showed highly selective and sensitive determination of nitrite with a good linear range of 250 μM to 10,000 μM with correlation coefficient of 0.998 and a sensitivity of 38.8 μAmM−1 cm−2. The limit of Detection of nitrite sensing system was 93 μM at a signal to noise ratio of 3. Also, the sensor showed prominent reproducibility, good stability, anti‐interference performance and also the prepared sensor was successfully used for the detection of nitrite in real samples. |
