摘要：
Perovskite La0.6Sr0.4Co0.2Fe0.8O3 nanofibers decorated with RuO2 nanoparticles (RuO2@LSCF-NFs) are prepared by electrospinning combined with a facile synthesis method. The obtained RuO2@LSCF-NFs are used as a cathode catalyst for lithium-oxygen (Li-O-2) batteries. The RuO2@LSCF-NFs catalyst exhibits enhanced catalytic performance with a decreasing voltage gap of 283mV lower than the cell with the LSCF-NFs catalyst. The improved performance is attributed to the superior catalytic activation of RuO2 nanoparticles toward oxygen evolution reaction (OER).
