olvated Metal Atom Dispersion is a method of producing highly reactive solvated nanoparticles, by just keeping them in an airtight container.
Solvated Metal Atom Dispersion is a method of producing highly reactive solvated nanoparticles. Samples of the metal (or ceramic) are heated to produce free atoms (or species), as in PVD evaporation. These are then co-depositied with a suitable organic frozen solvent (e.g. toluene) at very low temperatures (on the order of 70K). This is then warmed towards room temperature, producing solvated metal atoms or (over time) larger clusters. Sometimes, catalysts supports (such as SiO2 or Al2O3) are added to improve nucleation, as it can more readily take place on surface OH groups.
