Abstract
Official abstract text for this publication.
A method for electrolysis of water and a method for preparing a catalyst for electrolysis of water are provided. The method for electrolysis of water includes using a high entropy alloy as a catalyst. Further, the method for preparing a catalyst for electrolysis of water includes the steps of placing a substrate in an aqueous electrolyte containing a high entropy alloy precursor and performing an electroplating process on the substrate to form a high entropy alloy catalyst on the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing a catalyst for electrolysis of water, comprising: placing a substrate in an aqueous electrolyte containing a high entropy alloy precursor, wherein the high entropy alloy precursor comprises manganese chloride, ferric chloride, cobalt chloride, nickel chloride, cupric chloride and ammonium molybdate; and performing an electroplating process on the substrate to form a high entropy alloy catalyst on the substrate, wherein in the high entropy alloy catalyst, based on a total mole number of the high entropy alloy catalyst, a content of each of manganese, iron, cobalt, nickel, copper and the molybdenum is in a range of 5 to 35 at. %. 2. The method for preparing a catalyst for electrolysis of water according to claim 1 , wherein a current density of the electroplating process is in a range of 2 to 6 A/cm 2 . 3. The method for preparing a catalyst for electrolysis of water according to claim 1 , wherein the substrate comprises a porous substrate.
