Colloidal and microemulsion synthesis of rhenium nanoparticles in aqueous medium

- Re nanoparticles synthetized by simple colloidal and micremulsion method in aqueous medium.
- Higher mean size range for colloidal (0.7-2.8 nm) than for microemulsion synthesis (0.7-1.4 nm).
- Low size and narrow distribution achievable by slow addition of reducing agent.
- Faster/easier reduction and higher size observed for synthesis at high temperature in inert atmosphere.
