The stability of platinum‐based alloy catalysts is crucial for the future development of proton exchange membrane fuel cells, considering the potential dissolution of transition metals under complex operating conditions. Here, we report on a Rh‐doped Pt3Co alloy that exhibits strong interatomic interactions, thereby enhancing the durability of fuel cells. The Rh−Pt3Co/C catalyst demonstrates exceptional...

It is crucial to rationally design and synthesize atomic‐scale transition metal‐doped carbon catalysts with high electrocatalytic activity to achieve a high‐efficient oxygen reduction reaction (ORR). Herein, an electrocatalyst comprised of Fe–Fe dual atom pairs and N‐doped concave carbon are reported (N‐CC@Fe DA) that achieves ultrahigh electrocatalytic ORR activity. The catalyst is prepared by a...
The development of low platinum‐based alloy electrocatalysts is crucial to accelerate the commercialization of fuel cells, yet remains a synthetic challenge and an incompatibility between activity and stability. Herein, a facile procedure to fabricate a high‐performance composite that comprises Pt–Co intermetallic nanoparticles (IMNs) and Co, N co‐doped carbon (Co‐N‐C) electrocatalyst is proposed...
