Pd catalyst was deposited onto various carbide‐derived carbons (CDC) that were prepared from TiC, Mo 2 C and SiC. Specific surface area and pore size distribution of the Pd/CDC materials were measured. Microwave plasma assisted atomic emission spectroscopy was carried out to give information about the amount of Pd deposited. Scanning electron microscopy (SEM) studies revealed that CDC was uniformly covered by fine Pd particles, the size of which was further analysed by transmission electron microscopy (TEM). The oxygen reduction reaction (ORR) on Pd/CDC catalysts was studied in KOH and HClO 4 solutions. These electrocatalysts showed higher specific activities for ORR as compared to the commercial Pd/C.

碳化物衍生的碳载Pd催化剂上的氧电还原

Pd催化剂沉积在各种由TiC，Mo 2 C和SiC制成的碳化物衍生碳（CDC）上。测量了Pd / CDC材料的比表面积和孔径分布。进行了微波等离子体辅助原子发射光谱分析，以提供有关Pd沉积量的信息。扫描电子显微镜（SEM）研究表明，CDC被细小的Pd颗粒均匀覆盖，其尺寸通过透射电子显微镜（TEM）进一步分析。在KOH和HClO 4溶液中研究了Pd / CDC催化剂上的氧还原反应（ORR）。与市售Pd / C相比，这些电催化剂对ORR表现出更高的比活。
