Iron-Group and Amorphous Alloys: Promising Electrocatalysts For Alkaline Her - A Review
Main Article Content
Abstract
The drive for efficient and sustainable hydrogen production has prompted research into creating more effective electro-catalysts. By carefully synthesizing metal composite/alloy films through various deposition techniques, it's possible to fine-tune their electro-catalytic characteristics. This review explores the development and properties of promising electrocatalysts, particularly those based on iron-group elements (iron, nickel, or cobalt). Amorphous alloys, with their unique combination of electrochemical, mechanical, and corrosion-resistant properties, have attracted significant research interest. The review highlights molybdenum and phosphorus as especially effective elements for creating amorphous alloys, focusing on their co-deposition technique. Additionally, other metal groups like pure metals and rare-earth elements in alloyed composite forms are discussed. Finally, the review emphasizes the use of electrodeposition methods for preparing these alloys, particularly relevant for applications in the chlor-alkali industry.
