Abstract

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.

新型吲哚-氰基乙酸衍生物的合成、表征及其应用

本文设计并合成了新型有机催化剂 (E)-2-氰基-3-(5-(1-甲基-2-(萘-1-基)-1H-吲哚-3-基)呋喃-2-基)丙烯酸 (8)。首先，利用 Sonogashira 偶联反应、碘代环化反应、Suzuki-Miyaura 偶联反应和缩合反应制备了新型吲哚-氰基乙酸。然后进行了电化学研究，以考察阳极电催化剂的性能。电化学技术包括在 1 M KOH + 0.5 M N2H4 溶液中的循环伏安法（CV）和电化学阻抗谱法（EIS），用于确定催化剂的肼电氧化性能 (8)。此外，还利用理论计算找到了带隙能。我们的 D-A 型有机催化剂 (8) 的催化活性非常高，达到 24.67 mA/cm2。研究表明，D-A 型有机系统有可能成为肼燃料电池应用中对生态无害的阳极催化剂材料。

期刊介绍： The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
