Improving cost-effectiveness in proton-exchange-membrane fuel cells through the use of platinum (Pt) alloy nanoparticles as cathode catalysts is a clear objective. Recent research has focused on tailoring disordered structures into ordered intermetallic structures to enhance the performance and durability of alloy catalysts. This mini-review provides an overview of the current understanding of the formation mechanism of intermetallic nanoparticle catalysts and highlights advancements in synthesis methods for better size and composition control. Controversies surrounding the ordering effect of intermetallic nanoparticle catalysts are discussed, emphasizing the critical significance of ordered structures in developing advanced alloy catalysts.
Improving the cost-effectiveness of proton-exchange -membrane fuel cells by using platinum (Pt) alloy nanoparticles as cathode catalysts is a clear direction. To further enhance the performance and durability of alloy catalysts, tailoring disordered structures into ordered intermetallic structures has been a research focus in recent years. This mini-review sum-marizes the current theoretical understanding of the formation mechanism of intermetallic nanoparticle catalysts and recent advancements in synthesis methods that allow for better size and composition control. With a review of controversies sur-rounding the ordering effect of intermetallic nanoparticle cat-alysts, we further highlight the critical significance of ordered structures in developing advanced alloy catalysts.
