Özet

Herein, the novel organic catalyst, (E)-2-cyano-3-(5-(1-methyl-2-(naphthalen-1-yl)-1H-indol-3-yl)furan-2-yl)acrylic acid (8), was designed and synthesized. Initially, novel indole-cyanoacetic acid was prepared by using the Sonogashira coupling reaction, iodocyclization reaction, Suzuki–Miyaura coupling reaction, and condensation reactions. Then, electrochemical studies were carried out to investigate the anode electrocatalyst performance. Electrochemical techniques, including cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in a 1 M KOH + 0.5 M N2H4 solution, were employed to determine the hydrazine electro-oxidation performance of the catalyst (8). In addition, theoretical calculations were used to find band gap energies. Our D-A type organic catalyst (8) exhibits very high catalytic activity with 24.67 mA/cm2. D-A organic systems were shown to have the potential to be ecologically benign anode catalyst materials for hydrazine fuel cell applications.
