On account of the high‐cost of platinum, researchers are working to develop a new catalyst that is cheaper and has a catalytic effect equivalent to platinum. Herein, owing to the unique acetylenic bonds in graphdiyne, iron, nitrogen co‐doped graphdiyne (Fe‐N‐GDY) is a promising nonprecious metal catalyst, which has been developed with just a small amount of iron precursor with the plan to substitute it for Pt‐based catalysts. The as‐synthesized Fe‐N‐GDY composited catalyst shows excellent catalytic performance with the onset potential of 0.94 V versus reversible hydrogen electrode and limited current density of 5.4 mA cm−2. Moreover, it shows excellent resistance to methanol poisoning and stability in both acidic and alkaline electrolytes, which makes potentially applicable in the oxygen reduction reaction field. Doped graphdiyne: An efficient nonprecious metal electrocatalyst is synthesized by using novel graphdiyne (GDY) materials for the oxygen reduction reaction. Owing to the powerful synergistic effect between Fe, N, and GDY, the Fe‐N co‐doped GDY (Fe‐N‐GDY) catalyst has excellent catalytic activity in both alkaline and acidic media, comparable to Pt/C. Moreover, the stability and methanol tolerance of Fe‐N‐GDY are better than those of Pt/C. [ABSTRACT FROM AUTHOR]
