Metallic silver is deposited from a silver salt solution onto a support by reduction, and thus a catalytically active electrode material for oxygen-consuming electrodes is obtained. For this purpose, (a) an aqueous dispersion of a hydrophobic polymer, in particular a dispersion of PTFE, (b) a silver salt solution and (c) reducing agent for silver ions are mixed. During this, a pH at which the dispersion employed is stable, and the silver salt is reduced, should be maintained. |
