AI Technical Summary
In existing water electrolysis hydrogen production technologies, the oxygen evolution catalyst at the anode relies on precious metals, which is costly and has slow reaction kinetics. Furthermore, the stability and activity of doped spinel catalysts in different electrolytes are insufficient, making it difficult to meet industrial requirements.
By employing a low-temperature eutectic medium to induce precursor oxide lattice reshaping, efficient and uniform implantation of noble and rare earth metals is achieved, thus preparing a dual-doped spinel catalyst. This process suppresses low-stability surface adsorption and metal cluster formation, thereby enhancing the catalyst's structural stability and activity.
It exhibits excellent corrosion resistance and high stability in different electrolytes, significantly reducing the amount of precious metals required. Its catalytic performance is superior to commercial IrO2, and it is suitable for acidic, alkaline, and seawater media, showing promising prospects for industrial applications.
