Abstract

Solvent-stabilized transition metal colloids are prepared either electrochemically by cathodically reducing metal salts in the presence of polar stabilizing solvents to form metal colloids, or the transition metal salts are reduced in polar solvents using an alcohol at elevated temperatures.
