High-Performance Oxidation and Nanomolar Detection of Phenylhydrazine Using a 6-Hydroxyflavone-Based Molecular Electrocatalyst Functionalized Multiwalled Carbon Nanotube in Batch Injection Analysis.

ABSTRACT: The development of simple and rapid methods for preparing redox-active molecular catalyst-functionalized carbon electrodes for electrocatalytic applications is a significant research area. 6-Hydroxyflavone (HFLA), a naturally occurring flavonoid with known anxiolytic properties, also acts as a noncompetitive inhibitor of cytochrome. This study focuses on the in situ functionalization of multiwalled carbon nanotubes (MWCNTs) with redox-active HFLA, resulting in a modified electrode denoted as GCE/MWCNT@HFLA-Redox, where HFLA-Redox represents the redox-active product of HFLA. The constructed-modified electrode exhibits a well-defined and stable surface-confined redox response at E° of 0.55 V versus Ag/AgCl, with a surface excess of 6.26 × 10^-9 mol cm^-2 in a pH 2 KCl-HCl
