多壁碳纳米管（NTs）已被用作酸性介质中甲醇电氧化催化金属颗粒的有吸引力的载体。将Pt-Ru（50:50）纳米颗粒沉积在不同类型的纳米管材料上，以选择最佳载体并评估CH3OH氧化效率。在2500°C石墨化的纳米管上支持的Pt-Ru提供最佳的电压/电流特性，最大电流负载为2.7A/g。纳米管的介孔网络结合其优异的导电性能，使试剂分子能够快速运输和容易到达电极界面的催化位点，从而使甲醇阳极具有良好的性能。
Multiwalled carbon nanotubes (NTs) have been used as an attractive support of catalytic metallic particles for methanol electrooxidation in acidic medium. Pt–Ru (50:50) nanoparticles were deposited on the different type of nanotubular materials to select the best support and to estimate the efficiency of CH3OH oxidation. Pt–Ru supported on NTs graphitized at 2500°C supply the optimal voltage/current characteristics with a maximum current load of 2.7A/g. Mesoporous network of nanotubes combined with their excellent conducting properties allows a quick transport and easy accessibility of the reagent molecules to the catalytic sites of electrode interface giving a good performance of methanol anode.
