“…But single metallic nitrides show much lower activity compared to TMP for unfavorable M−H bonding strength. Moreover, unlike the P in TMP, N 3 strain between WC and W 2 N led to facile electron transfer from W 2 N to WC, strengthening the electronic interaction which boosted catalytic reactions. Cu 3 N is an interesting TMN which was explored as both HER and OER catalysts by Panda et al 177 Coordinately unsaturated Cu(I) at the Cu 3 N nanoparticle surface acted as an electro(pre)catalyst which converted to metallic Cu(0) and CuO species during reductive and oxidative potential runs, resulting in Cu 3 N@Cu and Cu 3 N@CuO core−shell structures, respectively.…”

“…Water splitting to afford hydrogen as a renewable energy source is one of the crucial ways to achieve alternative energy. − Ideally, it requires proton reduction at the cathodic compartment to produce hydrogen (eq ) and the hydrogen evolution reaction (HER) and simultaneous oxidation of water molecules at the anode compartment to generate oxygen (eq ) in the oxygen evolution reaction (OER). Interestingly, both half-cell reactions are pH sensitive following the Nernst equation, i.e., a 59 mV drop in potential per unit increment in pH and vice versa.…”

Critical Role of Interface Design in Acceleration of Overall Water Splitting and Hybrid Electrolysis Process: State of the Art and Perspectives

Electrocatalytic water splitting to hydrogen (H2) is an ideal approach to generate renewable energy. One of the major drawbacks is the tightly coupled kinetically sluggish and energy inefficient anodic oxygen evolution reaction (OER) with hydrogen forming a cathodic half-cell reaction which leads to a significant reduction in overall cell efficiency. In this context, before reviewing the literature, we have first briefly analyzed the energetics of overall water splitting, problems, and challenges under different pH conditions which can be useful for the further understanding of the process. Replacement of the anodic OER by a thermodynamically favorable substrate oxidation offers flexibility, value addition, and energy efficiency in the case of hybrid or assisted water electrolysis to afford hydrogen. Recent progress in terms of sacrificial oxidants in hybrid water electrolysis are discussed in this context, where the sacrificial oxidants are so chosen that the oxidation often leads to its value addition. Also here, we have offered insights into interface designing in heterostructures by modulating chemical and electronic environments for the enhancement of the intrinsic catalytic activity and stability. The effect of incorporation of such materials into the overall water splitting reaction, their catalytic active sites, and interactions with intermediates are thoroughly explored. This review can be a good complement for better understanding of the elucidation of the interface role in hybrid water electrolysis for future commercial applications.

Construct of an Electrodeposited Cobalt–Molybdenum Film and Evaluation of Its Efficiency in Hydrogen Evolution

Hydrogen is a valuable clean energy source, and electrolysis to produce hydrogen from water is a crucial component. However, a major problem of hydrogen generation by electrolysis is its large overpotential and poor economics. To reduce the overpotential, we mainly use nickel foam and Co−Mo ions as feedstock and create an efficient catalytic material by electrodeposition. The Co−Mo interaction improves the current efficiency. In 1 mol/L NaOH solution, the overpotential of the Co−Mo-NF composites was low when the current density is −10 mA/cm 2 , with the best value reaching 45.3 mV, which is less than those of Co-NF (94.4 mV) and Mo-NF (88.2 mV). All deposits had similar Tafel slopes in the 77.9 mV/decade range. The catalyst does not just have a favorable effect on hydrogen formation but also has a surprisingly high double-layer capacitance (up to 180 mF/ cm 2 ) and good stability. This research provides an impactful approach for developing a non-precious metal HER catalyst for industrial hydrogen production.

“…Although many studies have been conducted on decreasing the doping amount of rare and precious metals like Pt, Pd, and Ir, and the properties of these materials also have shown excellent performance, − the nonrenewable and scarce precious metals are still difficult to produce and use on a large scale. Transition metals, such as Ni, Mo, Fe, Co, and so on, have rich content, the alloy formed by each other, − and the transition metal-based compounds formed with P, B, S, N, and other elements have excellent electrolytic water hydrogen evolution performance − and will eventually become a substitute for precious metals . Among the transition metal-based compounds, numerous studies have proved that transition metal-based phosphates (TMPs) have excellent activity, abundant active sites, and long-term stability .…”

The development of electrocatalysts that have long-term stability under large current density is very crucial for hydrogen production via alkaline water electrolysis. In this paper, a novel ternary nonprecious metal catalyst NiMoP on nickel foam (NF) was prepared via an in situ one-step method. The overpotential of NiMoP/NF for hydrogen evolution reaction (HER) in 1 M KOH reaches only 34 and 135 mV at a current density of 10 and 100 mA cm–2, respectively. And the overpotential for HER only rose by 6 mV after 100 h of chronopotentiometry (CP) for HER in 1 M KOH. Its efficient and stable HER performance depends on the synergistic effect of Ni, Mo, and P elements in the electrode and a large electrochemical surface area which the unique crack structure obtained by adjusting the content of Mo provides. The cheap NiMoP/NF material has great potential for application in commercial alkaline water electrolysis hydrogen production.
