摘要

通过简单、快速的水热法合成了镍铁氧体（NiFe2O4）电催化剂。利用各种技术分析了电催化剂的组成和结构。使用循环伏安法、线性扫描伏安法和电化学阻抗光谱法研究了 NiFe2O4 在碱性介质中氧化甲醇、乙醇、丙醇和异丙醇等醇类的电催化活性。与其他醇氧化反应相比，甲醇氧化反应（MOR）表现出较低的过电位，这表明 NiFe2O4 是甲醇氧化反应的优良催化剂。

Nickel ferrite as an efficient electrocatalyst for alcohol oxidation reactions

Nickel ferrite (NiFe₂O₄) electrocatalyst was synthesized via a simple, rapid hydrothermal method. The electrocatalyst’s composition and structure were analyzed using various techniques. The electrocatalytic activity of NiFe₂O₄ toward the oxidation of alcohols such as methanol, ethanol, propanol, and isopropanol in an alkaline medium was studied using cyclic voltammetry, linear scan voltammetry, and electrochemical impedance spectroscopy. The methanol oxidation reaction (MOR) exhibited a lower overpotential than the other alcohol oxidation reactions, suggesting that NiFe₂O₄ is an excellent catalyst for MOR.
