Title: Highly durable nanoscale electrocatalyst based on core shell particles

Abstract

A multimetallic nanoscale catalyst having a core portion enveloped by a shell portion and exhibiting high catalytic activity and improved catalytic durability. In various embodiments, the core/shell nanoparticles comprise a gold particle coated with a catalytically active platinum bimetallic material. The shape of the nanoparticles is substantially defined by the particle shape of the core portion. The nanoparticles may be dispersed on a high surface area substrate for use as a catalyst and is characterized by no significant loss in surface area and specific activity following extended potential cycling.

Platinum-coated non-noble metal-noble metal core-shell electrocatalysts

Patent Adzic, Radoslav; Zhang, Junliang; Mo, Yibo; ...

Core-shell particles encapsulated by a thin film of a catalytically active metal are described. The particles are preferably nanoparticles comprising a non-noble core with a noble metal shell which preferably do not include Pt. The non-noble metal-noble metal core-shell nanoparticles are encapsulated by a catalytically active metal which is preferably Pt. The core-shell nanoparticles are preferably formed by prolonged elevated-temperature annealing of nanoparticle alloys in an inert environment. This causes the noble metal component to surface segregate and form an atomically thin shell. The Pt overlayer is formed by a process involving the underpotential deposition of a monolayer of amore » « less

Patent Adzic, Radoslav [Setauket, NY]; Mo, Yibo [Naperville, IL]; Vukmirovic, Miomir [Port Jefferson Station, NY]; ...

The invention relates to platinum-coated particles useful as fuel cell electrocatalysts. The particles are composed of a noble metal or metal alloy core at least partially encapsulated by an atomically thin surface layer of platinum atoms. The invention particularly relates to such particles having a palladium, palladium alloy, gold alloy, or rhenium alloy core encapsulated by an atomic monolayer of platinum. In other embodiments, the invention relates to fuel cells containing these electrocatalysts and methods for generating electrical energy therefrom.

Black GE based on crystalline/amorphous core/shell nanoneedle arrays

Patent Javey, Ali; Chueh, Yu-Lun; Fan, Zhiyong

Direct growth of black Ge on low-temperature substrates, including plastics and rubber is reported. The material is based on highly dense, crystalline/amorphous core/shell Ge nanoneedle arrays with ultrasharp tips (.about.4 nm) enabled by the Ni catalyzed vapor-solid-solid growth process. Ge nanoneedle arrays exhibit remarkable optical properties. Specifically, minimal optical reflectance (<1%) is observed, even for high angles of incidence (.about.75.degree.) and for relatively short nanoneedle lengths (.about.1 .mu.m). Furthermore, the material exhibits high optical absorption efficiency with an effective band gap of .about.1 eV. The reported black Ge can have important practical implications for efficient photovoltaic and photodetector applications onmore » nonconventional substrates. « less
