A straight forward method for immobilizing Pt-Co alloyed nanoparticles onto nitrogen-doped CNx nanotubes is presented. The as-prepared electrocatalysts exhibit good performance for oxygen reduction reaction in acidic medium arising from the high-dispersion and alloying effect of the Pt-Co nanoparticles and the intrinsic catalytic capacity of the CNx nanotubes.
本文提出了一种将 Pt-Co 合金纳米粒子固定在掺氮碳纳米管上的简单方法。所制备的电催化剂在酸性介质中对氧还原反应表现出良好的性能，这归因于 Pt-Co 纳米粒子的高分散性和合金效应以及碳纳米管的固有催化能力。
