Description
Fuel-cell electrodes can grow their own catalyst particles, a trick called exsolution, and mixed-metal particles promise tailored chemistry plus regeneration by dissolving back on demand. Blanca Delgado-Galicia and co-authors watched four metals, iron, nickel, cobalt, and copper, exit a complex perovskite at once, using neutron diffraction, surface spectroscopy, and microscopy at working temperatures.
Copper-rich particles ruled at seven hundred degrees, iron-rich alloys at higher heat. Long reduction split particles into two-faced Janus forms, since iron and copper refuse to mix. Uniform alloys dissolved back fully when re-oxidized; the split ones did not. Composition, it turns out, decides whether the regeneration promise holds.
