Abstract (en)

[origin: WO2007138345A1] A process for making high metal content stabilised metal nanoparticles, comprises decomposing at least one metal acetylide in the presence of a first solvent under reducing conditions to yield a metal colloid solution and then recovering metal nanoparticles as a precipitate by either evaporating the first solvent or adding a second solvent to the first solvent. The metal colloid solution obtainable as an intermediate by such a process and the high metal content stabilised metal nanoparticles obtainable as the final product of such a process are also disclosed.
