英文摘要	Boosting the durability of Pt riatioparticles by controlling the composition and morphology is extremely important for fuel cells commercialization. We deposit the Pt-Cu alloy nanoparticles over high surface area carbon in different metallic molar ratios and optimize the conditions to achieve desired material. The novel bimetallic electro-catalyst {Pt-Cu/PC-950 (15:15%)} offers exceptional electrocatalytie activity when tested for both oxygen reduction reaction and methanol oxidation reactions. A high mass activity of 0.043 mA/mu g(Pt) (based on Pt mass) is recorded for ORR An outstanding longevity of this electro-catalyst is noticed when compared to 20 wt Pt loaded either on PC-950 or commercial carbon. The high surface area carbon support offers enhanced activity and pievepts the nanoparticles from agglomeration, migration, arid disSolution as evident by TEM analysis.
