Title: Process for the electrochemical manufacture of silver containing catalysts
IPC: B01J37/34
Filed: 1972-07-29
Abstract: A process is disclosed whereby a silver containing catalyst is produced, in a particle size ranging from 300 to 1,500 A, through the pulsed electrolysis of a solution of a silver salt (e.g., silver nitrate) in the presence of a complexing agent (e.g., ammonia) wherein current is fed to the solution for spaced periods of a few seconds duration.
