AI Technical Summary
Existing palladium-based catalysts are expensive, scarce, and have poor durability. Transition metal sulfides such as CoS2 are prone to aggregation and are unstable, affecting the efficiency and sustainability of hydrogen production through water electrolysis.
The Pd@CoS2 nanocatalyst derived from ZIF-67 was used. By loading nano-Pd particles onto the surface of CoS2 to form a core-shell structure, the catalytic activity and stability were improved by utilizing the porous framework structure of ZIF-67 and the electronic modification effect of Pd.
The Pd@CoS2 catalyst achieves efficient and low-cost hydrogen production through water electrolysis. It exhibits excellent hydrogen evolution performance and stability in acidic solutions, making it suitable for large-scale industrial applications.
