Low-Pt content (5%) carbon-supported Pt–Ni–TiO2 nanotube electrocatalysts were prepared via a microwave-assisted polyol strategy. Physical and morphological properties of these electrocatalysts were characterized by X-ray diffraction (XRD), high resolution transmission electron microscope (HRTEM), and energy dispersive X-ray spectroscopy (EDX). Cyclic voltammetry and chronoamperometry studies clearly suggested that the Pt(5%)–Ni(10%)–TiO2 nanotube (10%) supported by Vulcan XC-72 is better than the commercial 20% Pt/C electrocatalyst for methanol electro-oxidation in direct methanol fuel cells (DMFCs).

用于直接甲醇燃料电池的低 Pt 含量碳负载 Pt-Ni-TiO2 纳米管电催化剂

通过微波辅助多元醇策略制备了低 Pt 含量 (5%) 碳负载的 Pt-Ni-TiO2 纳米管电催化剂。这些电催化剂的物理和形态特性通过 X 射线衍射 (XRD)、高分辨率透射电子显微镜 (HRTEM) 和能量色散 X 射线光谱 (EDX) 进行表征。循环伏安法和计时电流法研究清楚地表明，由 Vulcan XC-72 支持的 Pt(5%)-Ni(10%)-TiO2 纳米管 (10%) 在甲醇电氧化方面优于商业 20% Pt/C 电催化剂。直接甲醇燃料电池 (DMFC)。
