硼掺杂碳纳米管负载纳米Pd的甲酸电氧化性能

摘要

制备了高分散和窄尺寸分布的低载量（3．1％）钯纳米颗粒，负载在硼掺杂的碳纳米管上，与Pd／OCNTs （3．2％）催化剂相比，表现出了较好的甲酸电氧化性能。表面分析表明，Pd上的电子转移给B掺杂的碳纳米管，引起Pd的3d电子密度的提高，增强了其在甲酸氧化中的性能。%Low-loading Pd with high dispersions and narrow size distributions is nanosized on boron-doped car-bon nanotubes (Pd/BCNTs,3.1%) and exhibited higher formic acid oxidation performance in comparison to Pd on HNO3-treated CNTs (Pd/OCNTs,3.2%).Surface analyses reveal that the increased Pd 3d electron density caused by electron transfer from Pd to B-doped CNTs enhances the formic acid oxidation performance .
