Abstract The synthesis of single-site metal catalysts and their applications in fuel cells are comprehensive chemical experiment for scientific research. The metal atoms are highly dispersed in the nitrogen-doped graphene framework (denoted as M-NG) by simply heat-treating the mixture of metal salt and graphene oxide in ammonia gas. The catalytic materials were characterized by XRD, TEM, SEM, and HAADF-STEM. The activity of the catalyst in the oxygen reduction reaction was measured using KOH solution as the electrolyte to explore the application potential of the single-site metal catalyst in the fuel cell. Through this experiment teaching, the cutting-edge academic research results and practical skills are incorporated into experiments to improve students' comprehensive experimental operation skills and cultivate their interests in the exploration of scientific research.
