Key Points

This research aims to evaluate the electrocatalytic activity of Sr-doped Nd1-xSrxMnO3 perovskite oxides for the oxygen reduction reaction (ORR).
Prepared perovskite oxides using the sol-gel method.
Synthesized three variations with different Sr doping levels (x = 0.1, 0.2, 0.3).
Conducted evaluations of electrocatalytic properties towards ORR.
Maximal electrocatalytic activity observed for specific Sr doping levels.
Performance varies significantly based on the composition of the dopants.

Abstract

Nd 1− x Sr x MnO 3 perovskite oxides ( x = 0.1, 0.2, 0.3), designated as NSM-0.9, NSM-0.8, and NSM-0.7, were prepared by Sol–Gel method and their electrocatalytic properties towards ORR was evaluated.
