Particles on particles on particles: RuSexOy electrocatalysts with a cluster-like distribution of selenium on the surface of carbon-black-supported ruthenium nanoparticles are suitable replacements for platinum at the cathode side of methanol fuel cells. Carbon-supported RuSexOy nanoparticles are not completely covered by Se after reductive annealing at 800 °C; rather, Se clusters form on the Ru nanoparticles, while the rest of the surface is covered by oxygen.
