Journal ArticleDOI
Stabilization of Platinum Oxygen-Reduction Electrocatalysts Using Gold Clusters
TL;DR: It is demonstrated that platinum (Pt) oxygen-reduction fuel-cell electrocatalysts can be stabilized against dissolution under potential cycling regimes by modifying Pt nanoparticles with gold (Au) clusters, and data suggest that the Au clusters confer stability by raising the Pt oxidation potential.
Journal ArticleDOI
Hydrogen-evolution catalysts based on non-noble metal nickel-molybdenum nitride nanosheets.
Wei-Fu Chen,Kotaro Sasaki,Chao Ma,Anatoly I. Frenkel,Nebojsa Marinkovic,James T. Muckerman,Yimei Zhu,Radoslav R. Adzic +7 more
TL;DR: The first synthesis of NiMo nitride nanosheets on a carbon support (NiMoNx/C) is reported, and the high HER electrocatalytic activity of the resulting NiMoNX/C catalyst with low overpotential and small Tafel slope is demonstrated.
Journal ArticleDOI
Highly active and durable nanostructured molybdenum carbide electrocatalysts for hydrogen production
Wei-Fu Chen,Chiu Hui Wang,Kotaro Sasaki,Nebojsa Marinkovic,Wenqian Xu,James T. Muckerman,Y. Zhu,Radoslav R. Adzic +7 more
TL;DR: In this article, molybdenum carbide (β-Mo2C) nanoparticles are prepared by in situ carburization of ammonium molydate on carbon nanotubes and XC-72R carbon black without using any gaseous carbon source.
Journal ArticleDOI
Platinum monolayer fuel cell electrocatalysts
Radoslav R. Adzic,Junliang Zhang,Kotaro Sasaki,Miomir B. Vukmirovic,Minhua Shao,Jian Wang,Anand Udaykumar Nilekar,Manos Mavrikakis,J. A. Valerio,F. Uribe +9 more
TL;DR: In this article, a new class of electrocatalysts for the O2 reduction, and H2 and methanol oxidation reactions, consisting of a monolayer of Pt deposited on a metal or alloy carbon-supported nanoparticles, was described.
Journal ArticleDOI
Platinum monolayer electrocatalysts for O2 reduction: Pt monolayer on Pd(111) and on carbon-supported Pd nanoparticles
TL;DR: In this article, the kinetics of oxygen reduction were studied in acid solutions on Pt monolayers deposited on a Pd(111) surface and on carbon-supported Pd nanoparticles using rotating disk-ring electrode technique.
