Microstructure characterization and propane oxidation over supported Ru nanoparticles synthesized by the microwave-polyol method

▶ The supported Ru nanoparticles are very active and stable for propane oxidation. ▶ The 1.6 nm Ru nanoparticles exhibit higher activity than 6 nm nanoparticles. ▶ In oxygen atmosphere Ru nanoparticles possesses good stability up to 250 °C. ▶ The metallic and oxide Ru species plays important role for propane oxidation.
