Journal ArticleDOI
Platinum-based nanocages with subnanometer-thick walls and well-defined, controllable facets
Lei Zhang,Lei Zhang,Luke T. Roling,Xue Wang,Xue Wang,Madeline Vara,Miaofang Chi,Jingyue Liu,Sang-Il Choi,Jinho Park,Jeffrey A. Herron,Zhaoxiong Xie,Manos Mavrikakis,Younan Xia +13 more
TL;DR: Nanocages of platinum are fabricated by depositing a few atomic layers of platinum as conformal shells on palladium nanocrystals with well-defined facets and then etching away the Pd templates.
Journal ArticleDOI
Synthesis and Characterization of 9 nm Pt–Ni Octahedra with a Record High Activity of 3.3 A/mgPt for the Oxygen Reduction Reaction
Sang-Il Choi,Shuifen Xie,Minhua Shao,Jonathan H. Odell,Ning Lu,Hsin-Chieh Peng,Lesia Protsailo,Sandra Guerrero,Jinho Park,Xiaohu Xia,Jinguo Wang,Moon J. Kim,Moon J. Kim,Younan Xia +13 more
TL;DR: The synthesis of uniform 9 nm Pt-Ni octahedra with the use of oleylamine and oleic acid as surfactants and W(CO)6 as a source of CO that can promote the formation of {111} facets in the presence of Ni is reported.
Journal ArticleDOI
Atomic Layer-by-Layer Deposition of Pt on Pd Nanocubes for Catalysts with Enhanced Activity and Durability toward Oxygen Reduction
Shuifen Xie,Sang-Il Choi,Ning Lu,Luke T. Roling,Jeffrey A. Herron,Lei Zhang,Lei Zhang,Jinho Park,Jinguo Wang,Moon J. Kim,Zhaoxiong Xie,Manos Mavrikakis,Younan Xia +12 more
TL;DR: Both theoretical and experimental studies indicate that the ORR specific activity was maximized for the catalysts based on Pd@Pt2-3L nanocubes, which showed enhancements in specific activity and durability toward the oxygen reduction reaction (ORR).
Journal ArticleDOI
Pd@Pt Core-Shell Concave Decahedra: A Class of Catalysts for the Oxygen Reduction Reaction with Enhanced Activity and Durability.
Xue Wang,Xue Wang,Madeline Vara,Ming Luo,Hongwen Huang,Aleksey Ruditskiy,Jinho Park,Shixiong Bao,Shixiong Bao,Jingyue Liu,Jane Y. Howe,Miaofang Chi,Zhaoxiong Xie,Younan Xia,Younan Xia +14 more
TL;DR: A facile synthesis of multiply twinned Pd@Pt core-shell concave decahedra by controlling the deposition of Pt on preformed Pd decahedral seeds is reported, showing substantial enhancement in both catalytic activity and durability toward the oxygen reduction reaction (ORR).
Journal ArticleDOI
Atomic layer-by-layer deposition of platinum on palladium octahedra for enhanced catalysts toward the oxygen reduction reaction.

TL;DR: Calculations based upon periodic, self-consistent density functional theory suggested that the enhancement in specific activity for the Pd@PtnL octahedra could be attributed to the destabilization of OH on their PtnL*/Pd(111) surface relative to the {111} and {100} facets exposed on the surface of Pt/C.
