We report a facile and general approach for preparing ultrafine ruthenium nanocatalysts by using a plasma-assisted synthesis at <100 °C. The resulting Ru nanoparticles are monodispersed (typical size 2 nm) and remain that way upon loading onto carbon and TiO2 supports. This gives robust catalysts with excellent activities in both organosilane oxidation and the oxygen evolution reaction. Out in the cold: Supported ruthenium catalysts prepared by a novel cold plasma-assisted approach show excellent activity in two representative yet different reactions: organosilane oxidation and oxygen evolution.
