AI Technical Summary
Technical Problem
Existing noble metal-based catalysts suffer from scarcity and high cost in the oxygen evolution reaction (OER), while nickel-based catalysts require increased number of active sites and catalytic activity to improve electrochemical performance.
Method used
A catalyst electrode is formed by dispersing nickel and other metal catalyst alloy spheres on the surface of a nickel-based porous substrate, and by doping with C, F, and S elements and forming phosphide metal particles, combined with a specific process preparation method to improve catalytic activity.
Benefits of technology
It significantly improves the efficiency of the electrolysis unit, and the catalyst electrode exhibits excellent catalytic performance in the OER process, reducing the dependence on precious metals.
