Ultrafine cobalt and ruthenium clusters are deposited on carbon paper substrates by cluster beam deposition using a matrix assembly cluster source and a pulsed microplasma cluster source, respectively. When used to catalyze the oxygen evolution reaction (OER), the cobalt and ruthenium clusters show electrocatalytic performance superior to the state-of-the-art Ru/C and RuO2 nanoparticle catalysts on both a mass and a specific-surface-area basis. Typically, the cobalt clusters can deliver 10 mA cm–2 at a low overpotential of 320 mV and show a small Tafel slope of 50 mV dec–1 and a mass-based turnover frequency of 0.01 s–1 at an overpotential of 300 mV, outperforming many cobalt-based OER catalysts |
