“…[128] Besides, precious metals, such as Au and Pd in particular, have provided improved catalytic activity and stability to Pt-based ternary systems. Examples include various Pd-, Au-, and AuPd-based ternary compositions: PtPdRu, [129][130][131] PtPdCu, [132][133][134][135][136][137][138][139][140] PtPdRh, [141] PtCuAu, [142] PtPdNi, [143,144] PtPdAu, [145,146] PtPdAg, [147,148] PtCoAu, [149] and PtNiAu. [150,151] Yu and coworkers, in particular, have shown the excellent stability of PtPdCu nanostructures.…”

“…To overcome the energy shortages and environmental pollution, extensive research has focused on proton exchange membrane fuel cells and rechargeable metal–air batteries. The oxygen reduction reaction (ORR) as a key part of the above energy technologies limits their overall power performance owing to its intrinsically sluggish kinetics. , Platinum (Pt)-group noble metals are considered to be the best ORR electrocatalysts for their four-electron reduction of oxygen, , but their high cost, low abundance, poor durability, and poisoning by CO/methanol hinder their commercial applications. Therefore, design of new and effective electrocatalysts composed of transition-metal elements is pivotal for highly efficient ORR …”

“…The electrocatalytic properties of bi- or multi-metallic Pt-containing alloys reflect combinations of the features of individual metal components, as well as the possible synergistic interactions between them [ 66 ]. The improved catalytic activities, relative to those characteristic of the bare (pure) Pt metal, have been demonstrated using the combination of Pt with different metals, such as Pd, Au, Ag, Ni, Co, Cu, and Fe [ 4 , 6 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 ]. The observed enhanced electrocatalytic activities have been attributed to geometric (decrease in the Pt–Pt bond distances) and electronic (increase in the d-electron vacancy in Pt) factors, in addition to the interfacial structural changes affecting the adsorption (O 2 -molecule-activation) properties [ 76 , 77 , 78 ].…”
