Facile Synthesis of Zinc Cobaltate Nano flakes: An enhanced Electrochemical detection of Organic Pollutant 4-Nitrotoluene

Abstract

The current work, we have demonstrate an electrochemical determination of 4-nitrotoluene (4-NT) based on zinc cobaltate nanoflakes (ZnCo2O4; ZnC Nfs) The ZnC Nfs was synthesized by simple Coprecipitation method and its physicochemical properties were systematically studied with various analytical and spectroscopic techniques such as XRD, FESEM and EDX. Moreover, the proposed ZnC Nfs modified with Screen-printed carbon electrode (SPCE) after that directly used for the electrochemical determination (4-NT). The ZnC/SPCE shows an excellent electrochemical activity for the (4-NT) detection. The as prepared ZnC Nfs provide a highly selective and sensitive electrocatalyst for the (4-NT) determination with good linear range response 0.05μM- 385.5μM and low detection limit 0.044μM. The ZnC/SPCE electrochemical sensor established the outstanding selectivity, well stability and reproducibility.
