Title: High-Loading Intermetallic Pt₃Co/C Core–Shell Nanoparticles as Enhanced Activity Electrocatalysts toward the Oxygen Reduction Reaction (ORR)

Abstract

A facile, seed-mediated growth method and postannealing treatment have been employed to synthesize a single-phase 40% mass loading intermetallic Pt₃Co/Vulcan electrocatalyst, enabling the electrocatalytic layer to be thinner and thus lowering the mass transport resistance for the ORR in proton exchange membrane fuel cells (PEMFCs). These 40% Pt₃Co/C nanocatalysts exhibited superior kinetics toward the ORR, relative to a 20% Pt₃Co/C catalyst, and only showed a slight degradation in the half-wave potential and electrochemical surface area after a 4000-cycle stability test. The high activity and stability are attributed to a stable intermetallic Pt3Co core with a Pt shell two to three atomic layers thick, as well as to its good dispersion on the support. This seed-mediated growth approach and postannealing treatment provide a new strategy to ensure single-phase formation and uniform particle size distribution for other high-mass-loading binary intermetallic/alloy electrocatalyst systems and can contribute to the practical commercialization of PEMFCs, especially in high-current-density applications, such as automotive

Building Durable Multimetallic Electrocatalysts from Intermetallic Seeds

Journal Article Bueno, Sandra A. ; Ashberry, Hannah M. ; Shafei, Ibrahim ; ... - Accounts of Chemical Research

When combined with earth-abundant metals, Pt-based alloy nanoparticles (NPs) can be cost-effective electrocatalysts. However, these NPs can experience leaching of non-noble-metal components under harsh electrocatalytic conditions. In this work, the Skrabalak group has demonstrated a novel NP construct in which Pt-based random alloy surfaces are stabilized against non-noble-metal leaching by their deposition onto intermetallic seeds. These core@shell NPs are highly durable electrocatalysts, with the ability to tune catalytic performance by the core@shell architecture, surface alloy composition, and NP shape. This versatility was demonstrated in a model system in which random alloy (ra-) PtM surfaces were deposited onto ordered intermetallic (i-)more »« less

Revealing the atomic ordering of binary intermetallics using in situ heating techniques at multilength scales

Journal Article Xiong, Yin ; Yang, Yao ; Joress, Howie ; ... - Proceedings of the National Academy of Sciences of the United States of America

Ordered intermetallic nanoparticles are promising electrocatalysts with enhanced activity and durability for the oxygen-reduction reaction (ORR) in proton-exchange membrane fuel cells (PEMFCs). The ordered phase is generally identified based on the existence of superlattice ordering peaks in powder X-ray diffraction (PXRD). However, after employing a widely used postsynthesis annealing treatment, we have found that claims of “ordered” catalysts were possibly/likely mixed phases of ordered intermetallics and disordered solid solutions. In this work, we employed in situ heating, synchrotron-based, X-ray diffraction to quantitatively investigate the impact of a variety of annealing conditions on the degree of ordering of large ensembles ofmore »« less

Building Random Alloy Surfaces from Intermetallic Seeds: A General Route to Strain-Engineered Electrocatalysts with High Durability

Journal Article Gamler, Jocelyn T. L. ; Ashberry, Hannah M. ; Sang, Xiahan ; ... - ACS Applied Nano Materials

Pt-based catalysts are common in fuel cells but suffer from high cost and poor durability. To overcome these limitations, earth-abundant metals are often incorporated with Pt in core@shell architectures or through alloy formation. In this work, the concepts of a core@shell architecture, alloyed surfaces, and high-durability intermetallics are integrated into one nanostructure platform using seed-mediated co-reduction (SMCR). Specifically, random alloy PtM (where M = Ni, Co, Cu, or Fe) shells are deposited on intermetallic PdCu B2 seeds. Control of shell thickness and Pt:M ratios is also demonstrated, providing a general route to strain-engineered alloyed surfaces. The performance of these nanocatalystsmore »« less

Optimizing the ORR activity of Pd based nanocatalysts by tuning their strain and particle size

Journal Article Xiao, Weiping ; Liutheviciene Cordeiro, Marco Aurelio ; Gong, Mingxing ; ... - Journal of Materials Chemistry. A

Controlling of the particle size and surface strain is the key to tuning the surface chemistry and optimizing the catalytic performance of electrocatalysts. In this study, we show that by introducing both Fe and Co into Pd lattices, the surface strain of Pd nanocatalysts can be tuned to optimize their oxygen reduction activity in both fuel cells and Zn–air batteries. The Pd₂FeCo/C alloy particles are uniquely coated with an ultrathin Fe₂O₃ shell which is in situ formed during a thermal annealing treatment. The thin shell acts as an effective barrier that prevents the coalescence and ripening of Pd₂FeCo/C nanoparticles. Comparedmore »« less

Au-Doped Stable L1 ₀ Structured Platinum Cobalt Ordered Intermetallic Nanoparticle Catalysts for Enhanced Electrocatalysis

Journal Article Kuttiyiel, Kurian A. ; Kattel, Shyam ; Cheng, Shaobo ; ... - ACS Applied Energy Materials

Bimetallic Pt₃Co alloys are the commercial electrocatalysts for the oxygen reduction reaction in a fuel cell, but their high Pt loading and durability are a concern. Working toward the goal of reducing the amount of Pt and simultaneously increasing the activity and stability of the catalyst, we describe two new structures of ordered intermetallics consisting of Pt₄Co₅ nanocatalyst protected by Au atoms. Varying the temperature for the formation of the intermetallics, two distinct PtCo structural characteristics were observed in the nanoparticles: one with a simple intermetallic structure and the other with an intermetallic structure core protected by a shell ofmore »« less
