“…The electrochemical active surface area (ECSA) of ZIF-67@ZIF-8@Ru-900 was then evaluated, which is proportional to the double-layer capacitances (C dl ) obtained by CV test in the non-Faradaic region (Figure S17). 62,63 The C dl value of ZIF-67@ZIF-8@Ru-900 was determined to be 131.4 mF cm −2 , which is larger than that of ZIF-67@Ru@ZIF-8-900 (81.7 mF cm −2 ), ZIF-8@Ru-900 (58.0 mF cm −2 ), ZIF-67@Ru-900 (39.9 mF cm −2 ) and 20 wt % Pt/C (40.6 mF cm −2 ). Moreover, the charge transfer kinetics of ZIF-67@ZIF-8@Ru-900 was assessed by the EIS measurement.…”

The design and construction of an efficient, stable, and low-cost electrocatalyst are the main challenge for hydrogen evolution reaction (HER) via water splitting. Herein, a dual-active-site Co−Ru-based HER electrocatalyst (ZIF-67@ZIF-8@Ru-900) was derived from the core−shell zeolitic imidazolate framework (ZIF) structure of ZIF-67 and ZIF-8 with a controlled spatial metal loading position. Benefiting from the effective synergistic electronic interaction between Co and Ru sites, the 3D porous architecture, and the pyridinic N species, the as-prepared ZIF-67@ZIF-8@Ru-900 exhibited an outstanding HER performance, showing an overpotential of only 13 and 29 mV to reach a current density of 10 mA cm −2 in 1 M KOH and 0.5 M H 2 SO 4 , respectively, along with reliable catalytic stabilities.

The increasing demand for green hydrogen is driving the development of efficient and durable electrocatalysts for the hydrogen evolution reaction (HER). Nickel‐molybdenum (NiMo) alloys are among the best HER electrocatalysts in alkaline electrolytes, and here we report a scalable solution precursor plasma spraying (SPPS) process to produce the highly active Ni4Mo electrocatalysts directly onto metallic substrates. The NiMo coating coated onto inexpensive Ni mesh revealed an excellent HER performance with an overpotential of only 26 mV at −10 mA cm−2 with a Tafel slope of 55 mV dec−1. Excellent operational stability with minimum changes in overpotential were also observed even after extensive 60 hour high‐current stability test. In addition, we investigate the influence of different substrates over the catalytic performance and operational stability. We also proposed that a slow, but consistent, dissolution of Mo is the primary degradation mechanism of NiMo‐based coatings. This unique SPPS approach enables the scalable production of exceptional NiMo electrocatalysts with remarkable activity and durability, positioning them as ideal cathode materials for practical applications in alkaline water electrolysers.
