Abstract
The present invention relates to a method for the reductive production and stabilization of functional metal nanoparticles under mild conditions in ionic liquids from the associated soluble salt sources by using elemental hydrogen in the presence of a proton catcher, allowing to adjust the particle size and the size distribution thereof by the appropriate choice of the used ionic liquid.
