Magnetic‐Field‐Enabled Ultrafast Quench Synthesis of Single‐Atom Catalysts for Efficient Anion Exchange Membrane Water Electrolysis

Angewandte Chemie, EarlyView.
We report a universal magnetic‐field‐enabled quench strategy for the ultrafast synthesis of diverse single‐atom catalysts within seconds. This simple and low‐cost method yields highly active catalysts with excellent performance in anion exchange membrane water electrolysis. ABSTRACT Single‐atom catalysts (SACs) play a critical role in diverse catalytic

A comparison of composite metal foam's properties and other comparable metal foams

Materials Letters, 2009
Abstract New closed cell composite metal foams are processed using casting and powder metallurgy (PM) techniques. The foam is comprised of steel hollow spheres packed into a random loose arrangement, with the interstitial spaces between spheres occupied with a solid metallic matrix.

Amorphous metal foams

Scripta Materialia, 2006
As recently demonstrated, amorphous metal foams are highly ductile in compression, and thus offer attractive compromises in mechanical and physical properties between crystalline metallic and ceramic foams. Challenges associated with fabrication of amorphous metal foams are critically assessed in the context of current and future processing methods ...

Nanoporous Metal Foams

Angewandte Chemie International Edition, 2010
AbstractNanoporous metal foams (NMFs) have been a long sought‐after class of materials in the quest for high‐surface‐area conductive and catalytic materials. Herein we present an overview of newly developed synthetic strategies for producing NMFs along with an in‐depth discussion of combustion synthesis as a versatile and scalable approach for the ...
