“…The alloying effect of Pt with Pd leading to modification of the d‐band vacancies was studied by Tseng et. al [30] . The number of unfilled d‐states in the synthesized Pt 3 Pd nanorods is as low as 0.3056 suggesting that they have lower unfilled Pt d‐states, and more d‐band electrons transfer from Pd to Pt, leading to higher ORR activities than Pt/C [30] .…”

The activity of Pt towards oxygen reduction reaction (ORR) can be enhanced by alloying it with secondary metals. They can be grouped into three different classes: alloys, bimetallics and intermetallics. Although alloys and bimetallics exhibit enhanced performance, often they are limited by metal dissolution and resulted in poor durability. This invokes the need on the development of ordered intermetallics. In this minireview we comprehensively present the recent progress and developments of Pt3X alloys and intermetallics towards ORR. Additionally, major technical challenges and possible future research directions to overcome these challenges are discussed to facilitate further research in this area.

“…This structure also exhibited an excellent durability with only 5.88% loss of the initial ECSA after the 1000 potential cycles of ADT in alkaline solution, as compared to 40.4% loss of the commercial Pt/C catalyst. Wang's group [77,78] Pt , 40% Pt/C, E-TEK). After 13,500 potential cycles, only 4% mass activity was lost versus the 38% loss of that of Pt/C.…”

“…Similarly, two peaks located at 70.93 and 74.33 eV shown in Fig. 2d are derived from Pt 4f7/2 and Pt 4f5/2, while the corresponding standard value is 70.9 and 74.25 eV, respectively [28,29]. The two peaks can be split into two doublets, associated with Pt 0 and Pt 2+ chemical states [30].…”

Nanomagnetic CoPt truncated octahedrons: facile synthesis, superior electrocatalytic activity and stability for methanol oxidation

et al. 2016

Nanomagnetic CoPt truncated octahedral nanoparticles (TONPs) were successfully synthesised through a facile one-pot strategy. These single crystal CoPt TONPs with an average size of about 8 nm exhibit excellent electrocatalytic performance of both activity and stability for methanol oxidation reaction (MOR). The mass and specific activities of CoPt TONPs is 8 and 6 times higher than that of standard commercial Pt/C, respectively. After accelerated durability test (ADT), the loss of electrochemical surface area (ECSA) for CoPt TONPs is only 18.5%, which is significantly less than that of commercial Pt/C (68.2%), indicating that CoPt TONPs possess much better stability than commercial Pt/C in the prolonged operation. The Curie temperature of CoPt TONPs down to 8 nm is as high as 350 K with weak ferromagntism at room temperature (RT), which is greatly valuable for recycling in the eletrocatalytic applications.
