| 摘 要： | 在铁基催化剂(Fe-N-C)中引入金属铈，采用高温热解法合成了氮掺杂碳纳米管(NCNTs)高负载金属催化剂(Fe/Ce-NCNTs)。金属铈的引入能更好地促进碳纳米管(CNTs)的生长，锚定更多的铁原子，增加Fe—NX活性位点的数量。Fe/CeNCNTs催化剂在碱性介质中表现出良好的催化活性和稳定性，半波电位为0.86 V(vs RHE)。将Fe/Ce-NCNTs催化剂应用于铝空气电池(AABs)，其峰值功率密度可达142 mW·cm-2，在50 mA·cm-2电流密度下放电比容量达到865 mAh·g-1，在高电流密度负载下具有较高的电压。

| Abstract: | N-doped carbon nanotube (NCNTs) with highly loaded metal catalysts (Fe/Ce-NCNTs) were synthesized via high-temperature pyrolysis method with Fe-based catalysts introducing Ce metallic. Ce metal can better promote the growth of carbon nanotubes (CNTs), anchoring more iron atoms and increasing the number of Fe-NX active sites. A highly conductive 3D network structure facilitates oxygen diffusion, electron transfer, and transport of reac-tion products. The Fe/Ce-NCNTs catalysts exhibited good catalytic activity (the half wave potential was 0.86 V (vs RHE)) and stability in alkaline media. Moreover, the assembled Al-air batteries (AABs) with Fe/Ce-NCNT exhibited a high performance with a power density of 142 mW·cm-2 and discharge specific capacity of 865 mAh·g-1 at 50 mA· cm-2. Fe/Ce-NCNTs possessed high voltage under a high current density load. |
