Palladium-Nickel Nanoalloy Catalysts Possess Tunable Parameters That Affect Critical Atomic-Scale Structural Features

The Science
Scientists have discovered that for palladium-nickel catalysts, certain surface characteristics, measured at the atomic level, sped the creation of carbon dioxide from carbon monoxide. To reveal the optimal atomic neighborhood for surface chemical activity, high-energy x-rays were scattered by nanoparticles while they were exposed to a reactive chemical environment.

Researchers Exploit Bimetallic Nanocrystals into Nanoframes to Synthesize Durable Electrocatalysts

A team of researchers has synthesized a highly active and durable class of electrocatalysts by exploiting the structural evolution of solid Pt-Ni bimetallic nanocrystals into porous cage-like structures or nanoframes. This novel material significantly enhanced catalytic activity for the oxygen reduction reaction -- the splitting of an O2 molecule into two oxygen ions -- that is critical to fuel cells and potentially other electrochemical applications.
