Abstract
Official abstract text for this publication.
A catalyst composition and a use thereof are provided. The catalyst composition includes a support and at least one RuXMY alloy attached to the surface of the support, wherein M is a transition metal and X≥Y. The catalyst composition is used in an alkaline electrochemical energy conversion reaction, and can improve the energy conversion efficiency for an electrochemical energy conversion device and significantly reduce material costs.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of electrochemical energy conversion, comprising: producing an electrochemical energy conversion reaction by using a catalyst composition in an alkaline media, wherein the catalyst composition comprises: a support and at least one Ru X M Y alloy attached to a surface of the support, wherein M comprises nickel (Ni), cobalt (Co), iron (Fe), manganese (Mn), chromium (Cr), vanadium (V), titanium (Ti), copper (Cu), or zinc (Zn), and X≥Y, wherein the electrochemical energy conversion reaction is a hydrogen oxidation reaction or a hydrogen evolution reaction in an alkaline media, and the hydrogen evolution reaction is represented by 2H 2 O+2e − →H 2 +2OH − . 2. The method of electrochemical energy conversion of claim 1 , wherein X/Y of the Ru X M Y alloy is 1 to 50. 3. The method of electrochemical energy conversion of claim 1 , wherein the Ru X M Y alloy is 0.5 w % to 85 w % of a total mass of the catalyst composition. 4. The method of electrochemical energy conversion of claim 1 , wherein the support is a conductive material or a corrosion-resistant material. 5. The method of electrochemical energy conversion of claim 1 , wherein the support comprises a carbon material, metal oxide, or metal material.
