Elaboration and electrochemical characterization of new fused heterocyclic systems as organic electrodes

In this study, we created paste electrodes by blending graphite carbon and natural phosphate, with modifications using organic molecules.The objective of This study aims to create a streamlined method for characterizing specific organic products, providing a faster and simpler alternative to existing techniques.Cyclic voltammetry makes it possible to separate the properties of organic products, Through the emergence of distinct oxidation and reduction peaks.The existence of NO2 groups within the backbone of organic molecule A is manifested by the disappearance of the 1 V oxidation peak (P2), and its replacement by a reduction peak around approximately -0.5 V (P5).These electrodes were also characterized by the hydrogen peroxide reduction reaction, which showed that the CPE-NP-molecule A electrode has a very high activity towards this reaction; whereas, the second electrode CPE-NP-molecule B, does not promote this reduction.In the same way the antioxidant power of the two molecules has been deduced, we find that molecule A has a remarkable antioxidant power compared to that of molecule B.
