"Pt sub 3 /sub Co@Pt Core@shell Nanoparticles as Efficient Oxygen Reduc" by Yongchao Yang, Chunhui Tan et al.
Abstract Core-shell structured bimetallic platinum-metal (Pt−M) nanoparticles, as a new class of active and stable nanocatalysts, have shown many advantages in increasing the utilization of precious Pt and improving electrocatalytic performances. Here, a core-shell Pt Co@Pt supported on porous graphitic carbon (denoted as Pt Co@Pt/C) is synthesized via a simple thermal method, and further used as an efficient electrocatalyst for oxygen reduction reaction (ORR) in the direct methanol fuel cell. An atomic-resolution high-angle annular dark-field scanning transmission electron microscopy (HAAD...
