Abstract Bimetallic Ni and Ti nanoparticle-modified indium tin oxide electrode (Ni–Ti NPs/ITO) were prepared by a two-step ion implantation method, and their electrocatalytic activity toward the oxidation of ethanol and glycol was evaluated. The ion-implantation method is simple, low-cost and environmental friendly without the use of any binder. The Ni–Ti NPs/ITO electrode were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). SEM and AFM showed that the nanoparticles on the Ni–Ti NPs/ITO electrode had a small range of dispersion (10–20 nm) and high dispersion. Electrochemical performances were measured by cyclic voltammetry (CV) and chronoamperometrics. The Ni–Ti NPs/ITO electrode exhibited much higher electrocatalytic activity and stability for ethanol and ethylene glycol oxidation than NiNPs/ITO.

碱性溶液中乙醇和乙二醇在双金属镍钛纳米粒子修饰氧化铟锡电极上的电催化氧化

摘要 采用两步离子注入法制备了双金属Ni和Ti纳米颗粒修饰的氧化铟锡电极（Ni-Ti NPs/ITO），并评估了它们对乙醇和乙二醇氧化的电催化活性。离子注入法不使用任何粘合剂，简单、成本低、环保。Ni-Ti NPs/ITO 电极通过扫描电子显微镜 (SEM)、原子力显微镜 (AFM) 和 X 射线光电子能谱 (XPS) 进行表征。SEM 和 AFM 表明 Ni-Ti NPs/ITO 电极上的纳米颗粒具有小范围的分散（10-20 nm）和高分散。通过循环伏安法 (CV) 和计时电流法测量电化学性能。
