Novel conductive polycarbazolic polymer embedded with palladium nanoparticles as a highly sensitive electrochemical sensor for hydrazine detection.

ABSTRACT: To meet the demand for sensitive, trace-level hydrazine detection, we present a novel, high-sensitivity electrochemical sensor. We synthesized a novel carbazole-based conducting polymer (CRCP) as a distinctive host matrix, demonstrating exceptional stability, high redox potential, and excellent electrochemical properties. Subsequently, we developed an innovative electrochemical sensor by controllably embedding Pd nanoparticles (Pd) into this as-synthesized CRCP matrix using a simple cyclic voltammetry (CV) method to create a highly efficient Pd/PCz@GCE system for sensitive detection of hydrazine in alkaline media. The modified electrode exhibited significant electrocatalytic activity towards hydrazine oxidation. Notably, the FE-SEM analysis revealed an even distribution of spherical Pd nan
