Abstract
The present disclosure relates to an electrode for electrolysis which includes a metal base layer, and a coating layer containing a ruthenium oxide, a cerium oxide, and a nickel oxide, wherein the coating layer is formed on at least one surface of the base layer. The electrode for electrolysis of the present disclosure is characterized by exhibiting excellent durability and improved overvoltage.
Claims6
A method of preparing an electrode for electrolysis, the method comprising:
- applying a coating composition on at least one surface of a metal base;
- and
- coating by drying and heat-treating the metal base on which the coating composition has been applied,
- wherein the coating composition comprises a ruthenium precursor, a cerium precursor, a nickel precursor, and a urea,
- wherein a molar ratio of the ruthenium precursor to the nickel precursor is in a range of 100:5 to 100:15, and
- wherein a ruthenium element of the ruthenium precursor and the urea are included in a molar ratio of 100:30 to 100:90.
