Abstract
We report a high performance oxygen reduction reaction (ORR) catalyst based on vertically aligned, nitrogen-doped carbon nanotube (VA-NCNT) arrays. Characterization in conditions analogous to the operation of a polymer electrolyte membrane fuel cell show ORR taking place on the catalyst at a favorable reduction potential with a superior current density and greater rate constant.
摘要
我们报告了一种基于垂直排列的氮掺杂碳纳米管（VA-NCNT）阵列的高性能氧还原反应（ORR）催化剂。在类似于聚合物电解质膜燃料电池操作条件下的表征表明，ORR 在催化剂上以有利的还原电势发生，具有更高的电流密度和更大的速率常数。
