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.
Claims16
A size-selective electrochemical process for preparing soluble transition metal colloids or bimetallic colloids, said metal colloids or bimetallic colloids being stabilized by solvents exclusively and having particle sizes ranging from 1 to 15 nm, said process comprising electrochemically reducing transition metal salts in the presence of a polar stabilizing solvent to form said metal colloids or bimetallic colloids.
A size-selective process for preparing soluble transition metal colloids or bimetallic colloids, said metal colloids or bimetallic colloids being stabilized by solvents exclusively and having particle sizes ranging from 1 to 15 nm, said process comprising reducing transition metal salts by heating said transition metal salts in the presence of a polar stabilizing solvent and an alcohol as a reductant to form said metal colloids or bimetallic colloids.
