Journal ArticleDOI
Shape-dependent catalytic properties of Pt nanoparticles.
S. Mostafa,Farzad Behafarid,Jason R. Croy,Luis K. Ono,Long Li,Judith C. Yang,Anatoly I. Frenkel,Beatriz Roldan Cuenya +7 more
TL;DR: A correlation between the number of undercoordinated atoms at the nanoparticle surface and the onset temperature for 2-propanol oxidation was observed, demonstrating that catalytic properties can be controlled through shape-selective synthesis.
Journal ArticleDOI
Bimetallic Pt-Metal catalysts for the decomposition of methanol: Effect of secondary metal on the oxidation state, activity, and selectivity of Pt
TL;DR: In this paper, a study of methanol (MeOH) decomposition over a series of bimetallic Pt-M catalysts, with M = Au, Pd, Ru, Fe.
Journal ArticleDOI
Solving the Structure of Size-Selected Pt Nanocatalysts Synthesized by Inverse Micelle Encapsulation
Beatriz Roldan Cuenya,Jason R. Croy,S. Mostafa,Farzad Behafarid,Long Li,Zhongfan Zhang,Judith C. Yang,Qi Wang,Anatoly I. Frenkel +8 more
TL;DR: It is shown that this synthesis method leads to 3D NP shapes even for subnanometer clusters, in contrast to the raft-like structures obtained for the same systems via traditional deposition-precipitation methods.
Journal ArticleDOI
Support Dependence of MeOH Decomposition Over Size-Selected Pt Nanoparticles
TL;DR: In this article, the decomposition of methanol over Pt nanoparticles supported on a series of oxide powders was investigated and found to be cationic and the most active for decomposition.
Journal ArticleDOI
Electronic properties and charge transfer phenomena in Pt nanoparticles on γ-Al2O3: size, shape, support, and adsorbate effects.
Farzad Behafarid,Luis K. Ono,S. Mostafa,Jason R. Croy,Ghazal Shafai,Sampyo Hong,Talat S. Rahman,Simon R. Bare,B. Roldan Cuenya +8 more
TL;DR: A correlation between the NP size, number of surface atoms and coordination of such atoms, and the maximum hydrogen coverage stabilized at a given temperature is established, with H/Pt ratios exceeding the 1 : 1 ratio previously reported for bulk Pt surfaces.
