Ruthenium‐Induced Activation of Molybdenum‐Cobalt Phosphide for High‐Efficiency Water Splitting

Min Bi,
Ying Zhang,
Xiaohong Jiang
et al.

Abstract: Advancing green hydrogen production technologies relies heavily on the development of highly efficient and durable bifunctional catalysts for overall water splitting. Herein, this study reports the ruthenium‐modified hollow cubic molybdenum‐cobalt phosphide (Ru‐MoCoP) as exceptional performance electrocatalyst for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Theoretical calculations and experimental results indicate that the incorporation of Ru not only serves as an efficient active s… Show more

“…103 Through the doping of foreign atoms, the relative position between the center of the d-band and the Fermi energy level can be finely adjusted, 104,105 consequently enabling the fine-tuning of adsorption energy and efficiency for intermediates. Vacancy defects, such as oxygen vacancies in oxides, serve to lower the energy band of O 2p and Fermi levels 106 (Fig. 12a and b).…”

“…The electrochemical water-splitting technology for hydrogen production utilizes surplus electricity to electrolyze abundant water resources, offering the advantages of high safety, environmental cleanliness, and the generation of high-purity H 2 . 6–10 Water electrolysis predominantly comprises the hydrogen evolution reaction (HER) and the oxygen evolution reaction, 11,12 with the HER being an electrode reaction for generating high-purity H 2 . However, during electrolysis, the polarization phenomenon results in high overpotentials and sluggish reaction kinetics for the HER, 13–16 necessitating additional electrical energy.…”
