低载量Pt/M-N-C催化剂的电化学性能

减少铂的用量对于燃料电池中的氧还原反应(ORR)具有重要意义。根据本组密度泛函理论计算的预测，Pt/Cu-SAC对于氧的吸附较弱，应比Pt/C的ORR活性有所提高。在项目的支持下，本研究采用氮掺杂碳纳米管配位的铜单原子作为载体沉积铂纳米粒子(Pt/Cu-SAC)，结果表明，燃料电池的峰值功率密度为526 mW cm-2，为实现降铂目标提供了可行的方案。本工作主要记录了所制备催化剂的结构表征，半电池性能，全电池性能和计算分析数据，数据采集时间为2019年4月，数据量为34.4MB。

Reducing platinum loading is of great significance for the oxygen reduction reaction (ORR) in fuel cells. According to the predictions from density functional theory (DFT) calculations conducted by our research group, Pt/Cu-SAC exhibits weaker oxygen adsorption and is expected to have higher ORR activity than Pt/C. Funded by this project, this study employed copper single atoms coordinated with nitrogen-doped carbon nanotubes as the support to deposit platinum nanoparticles (Pt/Cu-SAC). The results demonstrated that the peak power density of the fuel cell reached 526 mW cm⁻², providing a feasible solution for achieving the goal of reducing platinum loading. This dataset primarily documents the structural characterization, half-cell performance, full-cell performance, and computational analysis data of the as-prepared catalyst. The data was collected in April 2019, with a total size of 34.4 MB.
