“…It may have originated from native oxide formation, which has been reported in electrodeposited NiB and NiCoB films. 31 For Ni-P-B/CP, the higher shift of elemental B 1 s peaks supported the electron transfer from the B to d orbital of Ni, 9,17,27 which is consistent with previously reported studies on the TMPB catalyst. [17][18][19] Figure 6 shows the relationship between the scaled current density at À0.15 V RHE as a function of elemental P content, which was calculated by excluding the oxidized P in the P 2p spectra.…”

Hydrogen production via water electrolysis, which is crucial for addressing climate change, is limited due to the high cost and insufficient activity of the catalyst. Binary-nonmetal transition metal compounds are promising candidates for the hydrogen evolution reaction (HER) owing to the synergetic effect between metal and nonmetal elements. Herein, we report the facile fabrication of Ni phospho-boride catalysts and their compositional effects on HER activity. By controlling the deposition conditions, the elemental compositions were changed to modulate their electronic structures. Particularly, the HER intrinsic activity showed a volcano relationship based on the elemental P content. The optimized catalyst was prepared on a highly roughened substrate, which could be used as a cathode for a proton exchange membrane electrolyzer (PEMWE) single cell. A current density of 1.08 A cm À2 was obtained at a cell voltage of 2.0 V, which is comparable to state-of-the-art PEMWE single cell comprising nonnoble cathodes.

[ 138 ] Compared to Ni–B, the Ni–Co–B exhibits better catalytic HER activity in 1 m KOH electrolyte, which shows an overpotential of 145 mV to reach 10 mA cm −2 and a Tafel slope of 125 mV dec −1 . The presence of Co can accelerate the intermediate reaction during the HER, and the unique microstructure of the Ni–Co–B film can provide more active surface areas, both of which contribute to the high catalytic HER performance.…”

Electrochemical water splitting driven by the electricity generated from renewable energy is an ideal sustainable approach for hydrogen production, where an efficient hydrogen evolution reaction (HER) electrocatalyst is indispensable. Ni-based electrocatalysts are widely investigated for HER in different electrolytes due to their advantages of high Earth abundance, remarkable corrosion resistance, efficient electrocatalytic performance, and high electrical conductivity. Although several Ni-based electrocatalysts exhibit catalytic HER performance comparable to that of state-of-the-art Pt catalysts, it is still lack of practical applications possibly due to the duration limitation. In order to promote the nextstep intensive studies and applications, it is important to systematically summarize the progress of Ni-based electrocatalysts for HER. Accordingly, this review article focuses on the recent advances in Ni-based electrocatalysts toward HER, which includes the mechanism of the electrocatalytic HER in different electrolytes and progresses in the Ni-based electrocatalysts toward HER. The preparation approaches, electrocatalytic activities, and overall performance comparison of the Ni-based electrocatalysts are systemically summarized based on Ni-based compounds, that is, phosphides, chalcogenides, nitrides, carbides, borides, alloys, and (hydro)oxides. The improvement modulation strategies including morphological/phase control, heterostructures/heterointerfaces, defect engineering, composite engineering, and heteroatom doping are thoroughly discussed. Finally, corresponding challenges and perspectives are proposed.

“…It is usually problematic to prepare such complex systems from a large-scale production viewpoint. Electrochemical deposition is one of the excellent and economical methods in which the multielement electrocatalysts with high electrocatalytic activity and stability can be prepared directly on substrates without an adhesive or binder. − For instance, Wang et al prepared Cu/Ni-Co electrocatalysts with a facile electrodeposition strategy, exhibiting good electrochemical activity and stability over 24 h.…”

Large-scale hydrogen production via electrochemical water splitting requires low-cost and efficient electrocatalysts that work well at high current densities with a low overpotential for the hydrogen evolution reaction (HER). Herein, we report the production of a NiCoSeP nanostructured electrocatalyst by a low-cost, one-step electrodeposition technique. The catalyst exhibits very high current densities at small overpotentials (100 mA cm–2 at 151 mV, 500 mA cm–2 at 286 mV, and 1000 mA cm–2 at 381 mV) in 1.0 M KOH electrolyte. Moreover, NiCoSeP shows excellent HER performance in an acidic medium with small overpotentials of 93 and 131 mV to deliver large current densities of 100 and 500 mA cm–2, respectively. The unique morphology of NiCoSeP, superhydrophilic, and superaerophobic properties could facilitate electrolyte diffusion and rapid delivery of the generated bubble, respectively. Our experimental data confirm that the advantages of the excellent HER activity and stability of NiCoSeP nanostructure originate from the high active surface area, bimetal double-anion effect, and enhanced mass transfer of reactants and hydrogen bubbles. This work may provide a promising way for rational design and simplify the synthesis process of practical electrocatalysts.
