  • Durability of catalysts under fuel cell reaction conditions is challenging for active nanoalloy electrocatalysts derived from platinum group metals and other transition metals. Here, the authors show that realloying in certain multimetallic nanoalloys plays a major role in enabling the high durability.

  • Traditional approach to oxidation catalysts relies on metal/oxide supported peripheral interfacial oxygen activity. Here the authors show surface oxygenation of platinum-alloyed multicomponent nanoparticles, and reveals irregular oscillatory kinetics associated with the surface oxygenated sites.

  • The precise understanding of the active phase under reaction conditions at the molecular level is crucial for the design of improved catalysts. Now, Strasser, Jones and colleagues correlate the high activity of IrNi@IrOx core–shell nanoparticles with the amount of lattice vacancies produced by the nickel leaching process that takes place before and during water oxidation, and elucidate the underlying structural-electronic effects.

  • The length scale at which phenomena such as ferroelectricity is still present is of fundamental relevance for nanoscale applications. A high-resolution transmission electron microscopy study now shows how ferroelectricity can persist in nanoparticles down to about 5 nm in diameter, pointing the way towards the ultimate size limit for ferroelectric applications.
