TL;DR: A highly active and durable class of electrocatalysts is synthesized by exploiting the structural evolution of platinum-nickel (Pt-Ni) bimetallic nanocrystals by exploitingThe starting material, crystalline PtNi3 polyhedra, transforms in solution by interior erosion into Pt3Ni nanoframes with surfaces that offer three-dimensional molecular accessibility.
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
Alkali-stabilized Pt-OHx species catalyze low-temperature water-gas shift reactions.
Yanping Zhai,Danny Pierre,Rui Si,Weiling Deng,Peter Ferrin,Anand Udaykumar Nilekar,Guowen Peng,Jeffrey A. Herron,David C. Bell,Howard Saltsburg,Manos Mavrikakis,Maria Flytzani-Stephanopoulos +11 more
TL;DR: Alkali ions added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H2O + CO → H2 + CO2) used for producing H2.
Journal ArticleDOI
Catalytically active Au-O(OH)x- species stabilized by alkali ions on zeolites and mesoporous oxides
Ming Yang,Sha Li,Yuan Wang,Jeffrey A. Herron,Ye Xu,Lawrence F. Allard,Sungsik Lee,Jun Huang,Manos Mavrikakis,Maria Flytzani-Stephanopoulos +9 more
TL;DR: The addition of alkali ions (sodium or potassium) to gold on KLTL-zeolite and mesoporous MCM-41 silica stabilizes mononuclear gold in Au-O(OH)x-(Na or K) ensembles and paves the way for using earth-abundant supports to disperse and stabilize precious metal atoms with alkali additives for the WGS and potentially other fuel-processing reactions.
Journal ArticleDOI
Palladium–platinum core-shell icosahedra with substantially enhanced activity and durability towards oxygen reduction
Xue Wang,Sang-Il Choi,Luke T. Roling,Ming Luo,Cheng Ma,Lei Zhang,Lei Zhang,Miaofang Chi,Jingyue Liu,Zhaoxiong Xie,Jeffrey A. Herron,Manos Mavrikakis,Younan Xia +12 more
TL;DR: This work reports a system based on palladium icosahedra that demonstrates an effective approach to the development of electrocatalysts with greatly enhanced activity and durability.
