METHOD OF SYNTHESIZING HIGH-EFFICIENCY BIFUNCTIONAL ELECTROCATALYSTS

Resumen de: US2025205696A1

Described herein relates to a method that may be used for synthesizing a bifunctional electrocatalyst for electrochemical water splitting. The method may involve anodically converting an electrodeposited iron-nickel alloy film into an iron-nickel-oxygen nanofilm, followed by sequential phosphorization and/or selenylation treatments via chemical vapor deposition to form a quaternary iron-nickel phosphoselenide nanoporous film. This self-supported catalyst can facilitate both hydrogen evolution and oxygen evolution reactions, improving electrolysis efficiency. The inclusion of selenium may enhance electrical conductivity and stabilize catalytic performance, while the nanoporous structure can optimize mass transport. The film may be used as both anode and cathode in a two-electrode electrolyzer, enabling hydrogen production from pure water or seawater. Notably, the catalyst can demonstrate high turnover frequency and low overpotential, potentially surpassing conventional noble-metal-based catalysts. The system's stability under prolonged operation may underscore its potential for scalable hydrogen generation, reducing reliance on fossil fuels and advancing renewable energy applications.
