Creation of a 2-Nitrophenol Sensor by Using ZrO2-Encapsulated Barium Oxide in the Presence of 4-Nitrophenol
By employing ZrO2 coupled barium oxide nanoparticles modified glassy carbon electrode (ZrO2 coupled BaO/GCE), we create a novel platform to sense the environmental contaminant 2-nitrophenol. Using XRD, FTIR, and SEM, the phase formation of BaO and ZrO2 coupled BaO nanomaterials was examined. In comparison to bare GCE, both ZrO2 coupled BaO-modified GCE and pure BaO-modified GCE demonstrate strong electrocatalytic activity towards 2-nitrophenol. The ZrO2 coupled BaO-modified sensing platform has good sensitivity for 2-nitrophenol measurement across a broad linear range of 0.2 to 60 µM, with a 0.09 µM detection limit at the lowest. Moreover, it exhibits strong selectivity towards significant interfering substances including 4-nitrophenol, 4-aminophenol, catechol, hydroquinone, etc. Good agreement is observed between the analytical application of the suggested sensor and actual real water sample analysis.
