Abstract

The invention relates to gold-coated particles useful as fuel cell electrocatalysts. The particles are composed of an electrocatalytically active core at least partially encapsulated by an outer shell of gold or gold alloy. The invention more particularly relates to such particles having a noble metal-containing core, and more particularly, a platinum or platinum alloy core. In other embodiments, the invention relates to fuel cells containing these electrocatalysts and methods for generating electrical energy therefrom.

Dealloyed Pt-Cu Core-Shell Nanoparticle Electrocatalysts for Use in PEM Fuel Cell Cathodes

Journal Article Mani, P ; Srivastava, R ; Strasser, P - J. Phys. Chem. C112:2770,2008

We report the synthesis, characterization, and single fuel cell testing of a novel class of nanostructured Pt-Cu alloy particle materials for use as oxygen reduction electrocatalyst in polymer electrolyte membrane fuel cells. The active phase of the Pt alloy nanoparticle catalysts is prepared by electrochemical dissolution (voltammetric dealloying) of Cu surface atoms from Cu-rich Pt-Cu alloy precursors. Bulk and surface structural and compositional characterization suggests that the dealloyed active catalyst phase consists of a core-shell structure in which a multilayer Pt rich shell is surrounding a Pt-poor alloy particle core. The electrocatalytic Pt mass activity of the dealloyed core-shell particlesmore »« less
Engineering Platinum Alloy Electrocatalysts in Nanoscale for PEMFC Application

Conference He, Ting

Fuel cells are expected to be a key next-generation energy source used for vehicles and homes, offering high energy conversion efficiency and minimal pollutant emissions. However, due to large overpotentials on anode and cathode, the efficiency is still much lower than theoretically predicted. During the past decades, considerable efforts have been made to investigate synergy effect of platinum alloyed with base metals. But, engineering the alloy particles in nanoscale has been a challenge. Most important challenges in developing nanostructured materials are the abilities to control size, monodispersity, microcomposition, and even morphology or self-assembly capability, so called Nanomaterials-by-Design, which requires interdisciplinarymore »« less

Platinum-monolayer Electrocatalysts: Palladium Interlayer on IrCo Alloy Core Improves Activity in Oxygen-reduction Reaction

Journal Article Gong, K ; Chen, W -F ; Sasaki, K ; ... - Journal of Electroanalytical Chemistry

We describe the synthesis and electrocatalytic properties of a new low-Pt electrocatalyst consisting of an IrCo core, a Pd interlayer, and a surface Pt monolayer, emphasizing the interlayer's role in improving electrocatalytic activity for the oxygen-reduction reaction on Pt in HClO{sub 4} solution. We prepared the IrCo alloys by decomposing, at 800 C, hexacyanometalate, KCoIr(CN){sub 6}, adsorbed on the carbon surfaces. The synthesis of Ir{sub 3}Co/C involved heating a mix of metal salts and carbon in hydrogen at 500 C. Thereafter, we placed a palladium and/or platinum monolayer on them via the galvanic displacement of an underpotentially deposited copper monolayer.more »« less
