Bimetallic nanoparticle synthesis just got simpler

The process of synthesizing bimetallic nanoparticles from organometallic precursors no longer requires an organic solvent and stabilizers (which must be treated after processing). A team of researchers at Leti experimented with ionic liquids and obtained stable suspensions that can be applied directly to high-tech substrates.
The ionic liquids—salts dissolved at ambient temperature—have some surprising properties. The researchers have already used them to obtain ruthenium, copper, nickel, platinum, tantalum, and magnesium nanoparticles with perfectly-controlled sizes and structures. For example, the team produced 2 nm to 3 nm ruthenium-copper nanoparticles with a ruthenium core and copper shell.
The research is being conducted in conjunction with ESCPE Lyon at the Nanochemistry Platform.
