Osmium and OsOx nanoparticles: an overview of syntheses and applications [PDF]
Open Research Europe, 2022 Precious metal nanoparticles are key for a range of applications ranging from catalysis and sensing to medicine. While gold (Au), silver (Ag), platinum (Pt), palladium (Pd) or ruthenium (Ru) nanoparticles have been widely studied, other precious metals are less investigated. Osmium (Os) is one of the least studied of the precious metals.

Synthesis and controlled growth of osmium nanoparticles by electron irradiation [PDF]
Dalton Transactions, 2015 Defined-size osmium nanoparticles (1.5–50 nm) were synthesized on a B- and S-doped turbostratic graphitic structure from an organometallic osmium complex encapsulated in self-spreading polymer micelles and characterised by (HR)TEM, AFM and XPS.

Tripodal Osmium Polypyridyl Complexes for Self-Assembly on Platinum Nanoparticles [PDF]
The Journal of Physical Chemistry Letters, 2011 The combination of platinum nanoparticles with a tripodal osmium complex that anchors to the metal surface leads, under visible light irradiation, to the formation of solvated electrons. The formation kinetics is limited by the detachment of the electron from the platinum surface into the solution, the particle showing a type of capacitor behavior.
