Experiments show improved catalytic performance in hydrogen production with nanoporous metallic glass, indicating its potential for energy conversion.
The water splitting is a promising method for hydrogen production. The efficiency of the hydrogen evolution reaction (HER) is largely dependent on the efficient electrocatalyst with high activity and long‐term stability. In this work, a Ni active layer is prepared on the ligament surface of self‐supporting nanoporous CuZrAl metallic glass (np‐CuZrAl MG) through physical vapor deposition (PVD). Then, a trace amount of Pt is doped on the Ni active layer by a galvanic replacement (GR) reaction. The as‐formed Pt/Ni/np‐CuZrAl MG exhibits outstanding catalytic performance for HER with the low overpotential of 58 mV at a current density of 10 mA cm −2 . Also, the Pt/Ni/np‐CuZrAl MG presents good long‐term stability due to the self‐supporting structure and excellent mechanical property. This work offers valuable insights for the development of efficient catalysts, particularly in energy conversion and storage applications.
