SYNTHESIS OF BENZO[B]THIOPHENE-BASED ORGANIC COMPOUNDS AND THEIR HYDRAZINE ELECTROOXIDATION PERFORMANCE AS AN ANODE CATALYST

Abstract

In this study, 3-iodo-2-(p-tolyl)benzo[b]thiophene (4C) is synthesized by using Sonagashira coupling reactions and electrophilic cyclization reactions. Electrochemical measurements have been performed using electrochemical methods such as cyclic voltammetry (CV), chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS) in the environment of 1 M KOH + 0.5M N2H4 solution. The CV results obtained showed that 4C catalyst promoted the generation of the best current (15.40 mA/cm2), and EIS results confirmed that electrode modifeed with the same derivative presented the lowest charge transfer resistance. Taken together, these results suggest that 4C organocatalyst could be used as an anode efficient catalyst in hydrazine (N2H4) fuel cells.
