Pt-Ni nanourchins as electrocatalysts for oxygen reduction reaction

Qiaowan CHANG, Yuan XU, Shangqian ZHU, Fei XIAO, Minhua SHAO

Frontiers in Energy 2017, Volume 11, Issue 3, Pages 254-259 doi: 10.1007/s11708-017-0493-3

Abstract: Pt-Ni bimetallic alloys with various nanostructures have shown excellent activity toward oxygen reduction reaction (ORR). The ORR activity is highly dependent on the structure of the catalyst. In this paper, Pt-Ni nanourchins were synthesized with an average size of 50 nm consisting of 10–20 nanorods and nanooctahedra by adjusting the synthesis condition. The formation of Pt-Ni nanourchins is mainly dependent on the adding order of solvents (benzyl ether, oleylamine and oleic acid). Pt-Ni nanourchins present a reasonable high ORR activity (0.81 A/mg at 0.9 V).
