Abstract
PCT No. PCT/EP79/00020 Sec. 371 Date Nov. 28, 1979 Sec. 102(e) Date Nov. 26, 2979 PCT Filed Mar. 27, 1979 PCT Pub. No. WO79/00840 PCT Pub. Date Oct. 18, 1979 An electrode for electrolytic processes such as the recovery of uranium dioxide from seawater comprises an electrically-conductive corrosion-resistant substrate having an electrocatalytic coating which is preferably a mixture of 30 to 80 parts by weight of platinum, 20 to 70 parts by weight (as Mn metal) of .beta.--MnO.sub.2 and 2 to 10 parts by weight (as Sn metal) of tin dioxide.
Claims5
An electrode for electrolytic processes, comprising an electrically-conductive corrosion-resistant substrate having an electrocatalytic coating, characterized in that the coating contains a mixture of at least one platinum group metal and manganese dioxide dispersed in one another throughout the coating in a ratio of from 8:2 to 3:7 by weight of the platinum group metal(s) to the manganese metal of the manganese dioxide.
