Metal salts via anodic dissolution

In an electrochemical way of making metal nanopartides, a solution of stabilizer e.g., tetraalkylammonium bromide in THF) is electrolyzed using an anode made of the metal of interest and an inert cathode.l Under the conditions of the electrolysis, dissolution of the anode material takes place via oxidation. The metal cations transfer to the cathode, where reduction, nucleation and finally stabilization occur. The size of thus-prepared nanopartides can be easily controlled by the current density. The method is applicable to many transition metals. Moreover, systems with two anodes of different metals result in the formation of bimetallic nanopartides. When oxidation of the anode metal is difficult, the metal of interest can be introduced as inorganic salt.h67] pd nanopartides, e.g., prepared via this method were found to be catalyticaUy active in the Heck reaction and the...
