“…82 In addition to the elemental doping and surface modification, designing bimetallic or trimetallic pre-catalysts with the optimal composition could also promote the electrochemical processes for boosting the UOR catalysis. [83][84][85][86][87][88][89][90][91][92][93] Therefore, conducting elemental incorporation with favorable intermetallic interactions would be an effective method to accelerate the pre-oxidation reaction and thus facilitate the UOR process. For example, the Yu group fabricated a NiMoO 4 porous nanorod catalyst from NiMoO 4 ÁxH 2 O nanoarrays via a thermal treatment route, which displays remarkable UOR activity with a low UOR onset potential of 1.350 V vs. RHE, even surpassing Pt/C and RuO 2 .…”

Summary The nickel foam (NF) precursors were doped with nickel, cobalt particles with various chemical compositions; the most convenient one was decorated with silver nano‐domes and investigated for hydrogen production efficiency (HPE) in 1 M KOH. The X‐ray diffraction, field emission scanning electron microscopy, and energy‐dispersive X‐ray techniques were used to characterize the catalysts. Linear sweep voltammetry, cyclic voltammetry, Tafel polarization measurements, electrochemical impedance spectroscopy, and chronoamperometry were used to determine the electrochemical efficiency. The rough structured Ni‐ and Co‐deposited NF significantly increased the HPE achieved with silver nano‐domes particles decoration (NF/NiCo‐2/Ag). The results showed that NF/NiCo‐2/Ag was the most efficient catalyst, as it has lower hydrogen overpotential and a higher HPE, which was detected in polarization curves, as well as being stable during the 1 × 104 s electrolysis period and having a good response during electrochemical analysis. The produced hydrogen gas volume was 108.1 mL by using NF/NiCo‐2/Ag, at the end of 30‐minute electrolysis in 1 M KOH.

This study presents an innovative, statistically‐guided magnetron sputtering technique for creating nanoarchitectonics of high‐performing, NiFeMoN electrocatalysts for oxygen evolution reaction (OER) in water splitting. Using a central composite face‐centered (CCF) design, 13 experimental conditions are identified that enable precise optimization of synthesis parameters through response surface methodology (RSM), confirmed by analysis of variance (ANOVA). The statistical analysis highlighted a interaction between Mo% and N% in the nanostructured NiFeMoN and found optimizing values at 31.35% Mo and 47.12% N. The NiFeMoN catalyst demonstrated superior performance with a low overpotential of 216 mV at 10 mA cm−2 and remarkable stability over seven days, attributed to the modifications in electronic structure and the creation of new active sites through Mo and N additions. Furthermore, the NiFeMoN coating, when used as a protective layer for a Si photoanode in 1 m KOH, achieved an applied‐bias photon‐to‐current efficiency (ABPE) of 5.2%, maintaining stability for 76 h. These advancements underscore the profound potential of employing statistical design for optimizing synthesis parameters of intricate catalyst materials via magnetron sputtering, paving the way for accelerated advancements in water splitting technologies and also in other energy conversion systems, such as nitrogen reduction and CO2 conversion.
