Abstract—

Nanodispersed molybdenum sulfide decorated with platinum nanoparticles is proposed as a new catalytic nanosystem for a Li–O₂ battery. Using platinum as a catalytically active material reduces the overvoltage during charging. Due to the chemical stability of molybdenum sulfide as a support material, the current and power parameters of the system increase to 1000 mA/g, while the number of cycles during uninterrupted operation of the cell reaches 130 (for 500 mA/g). The catalytic system proposed in this study features bifunctional properties and high stability during cycling.

PtMoS 2作为用于Li–O 2电池的稳定双功能催化剂

摘要—

提出了用铂纳米颗粒修饰的纳米分散硫化钼，作为一种用于Li-O ₂电池的新型催化纳米系统。使用铂作为催化活性材料可减少充电过程中的过电压。由于作为支撑材料的硫化钼的化学稳定性，系统的电流和功率参数增加到1000 mA / g，而电池不间断运行的循环次数达到130（对于500 mA / g）。在这项研究中提出的催化系统具有双功能特性和循环过程中的高稳定性。
