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 .
