Abstract
The Pt@Au catalysts demonstrate remarkably high oxygen reduction reaction (ORR) activity compared with Pt/C catalysts. The ORR of Pt(2)@Au(1)/C and Pt(1)@Au(2)/C is 9.5 and 6.6 times that of Pt/C, respectively. This improvement is attributed to the electronic structure effect of the Au core on the Pt shell and introduction of PFSA.
摘要
Pt@Au 催化剂相较于 Pt/C 催化剂表现出了极高的氧还原反应（ORR）活性。Pt(2)@Au(1)/C 和 Pt(1)@Au(2)/C 的 ORR 活性分别是 Pt/C 的 9.5 倍和 6.6 倍。这种改善归因于 Au 核对 Pt 壳的电子结构效应以及 PFSA 的引入。
