Abstract
The process for the manufacture of cathodes suitable for use in electrolysis comprising depositing onto an electrically conductive substrate at least one layer of said Group VIII metal salts, one of which is a platinum group metal and then subjecting the whole to a heat treatment to oxidize said salts to the oxide form.
Claims6
The process for the manufacture of a cathode having an electrically conductive substrate bearing a coating consisting essentially of at least two oxides of a metal of Group VIII of the Periodic Classification of the Elements, at least one of which is a platinum group metal and at least another of which is a nonprecious metal;
- comprising depositing in the form of scales onto a nonetched electrically conductive substrate at least one layer of said Group VIII metal salts from a solution or suspension, and then subjecting the whole to a heat treatment to oxidize said metal salts to the oxide form.
