Title:
ELECTRODE FOR ELECTROLYSIS
Document Type and Number:
WIPO Patent Application WO/2018/097069
Kind Code:
A1
Abstract:
This electrode for electrolysis is provided with a conductive base material and a catalyst layer that is formed on the surface of the conductive base material. The catalyst layer contains elemental ruthenium, elemental iridium, elemental titanium and at least one first transition metal element selected from the group consisting of Sc, V, Cr, Fe, Co, Ni, Cu and Zn; the content ratio of the first transition metal element contained in the catalyst layer relative to 1 mole of the elemental titanium is 0.25% by mole or more but less than 3.4% by mole; and the D value serving as an index for the electric double layer capacity of this electrode for electrolysis is from 120 C/m2 to 420 C/m2 (inclusive).
