Abstract

On account of the high‐cost of platinum, researchers are working to develop a new catalyst which is cheaper and has a catalytic effect that is equivalent to platinum. Herein, owing to the unique acetylenic bonds in the graphdiyne, the iron‐nitrogen‐doped graphdiyne (Fe‐N‐GDY) as a new promising nonprecious metal catalyst is developed with just a small amount of iron precursor to substitute for Pt‐based catalysts. The as‐synthesized Fe‐N‐GDY composited catalyst shows excellent catalytic performance with the onset potential of 0.94V versus RHE and limited current density of 5.4 mA cm‐2. And it shows good resistance to methanol poisoning and stability in both acidic and alkaline electrolytes, which makes it the potential application in oxygen reduction reaction field.
