Abstract The key ongoing challenge is to design and develop effective inexpensive oxygen reduction reaction (ORR) catalysts replace Pt‐based ones for commercial use in fuel cells. Owing its abundance tunable electronic properties, the current work, synthesis of highly dispersed mixed valent copper oxide electrocatalyst reported. EC exhibits a high mass activity 9.8 mA mg −1 density 5.3 cm −2 contrast benchmark (20 wt%) Pt/C catalyst 0.1‐M KOH solution ORR. significantly electrochemical at cathode believed be due presence Cu(II)/Cu(I) redox pair. Furthermore, has been shown stable, maintaining retention 78% up 24 h. engineered material also active evolution reaction, making it viable replacement conventional alkaline
