“…This indicates that ZIF underwent a thermal decomposition when calcinated at 600 °C for 2 h under the protection of N 2 , 27 and that Co 2+ and Zn 2+ ions were thermally reduced at the same time to form Co 3 ZnC compounds. 28 The porous carbon was the result of the high-temperature carbonization of the organic ligand in ZIF. 29 Meanwhile, the presence of Ag peaks indicates that the calcination process did not significantly affect the structure of the Ag NPs.…”

Electrochemical water splitting to produce green hydrogen offers a promising technology for renewable energy conversion and storage, as well as realizing carbon neutrality. The efficiency, stability, and cost of electrocatalysts toward hydrogen evolution reaction (HER) and electrocatalytic overall water splitting (EOWS) at large current densities are essential for practical application. In this review, the key factors that determine the catalytic performance of electrocatalysts at large current densities are summarized from the angel of thermodynamic and kinetic correlation. The corresponding design strategies are presented. The electronic structure and density of active sites that affect the adsorption/desorption of intermediates are considered as the thermodynamic aspects, while charge transfer and mass transport capabilities closely associated with electrode resistance and intermediate diffusion are assigned as kinetic effects. Recent development of bifunctional and integrated electrocatalysts toward EOWS is also discussed in detail. Finally, the perspective and direction on the electrocatalytic water splitting under large current density are proposed. This comprehensive overview will offer profound insights and guidance for the continued advancement of this field.
