==OXYGEN EVOLUTION CATALYST HAVING CORE-SHELL STRUCTURE INCLUDING IRIDIUM OXIDE AND RUTHENIUM OXIDE, AND METHOD OF PREPARING SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18328908 titled 'OXYGEN EVOLUTION CATALYST HAVING CORE-SHELL STRUCTURE INCLUDING IRIDIUM OXIDE AND RUTHENIUM OXIDE, AND METHOD OF PREPARING SAME

The abstract describes an oxygen evolution catalyst with a core-shell structure containing iridium oxide and ruthenium oxide, and a method for its preparation.

* The catalyst is prepared by forming a core of nickel sulfide, growing a coating layer of iridium and ruthenium on the core surface to create nanoparticles, and heat-treating the nanoparticles to obtain the catalyst with a core and a shell of iridium oxide and ruthenium oxide.
* The core-shell structure enhances the catalytic activity of the oxygen evolution catalyst.
* The inclusion of iridium oxide and ruthenium oxide in the shell improves the efficiency of oxygen evolution reactions.
* The method allows for the precise control of the catalyst composition and structure, leading to improved performance in oxygen evolution processes.
