“…Recently, heterogeneous catalysts of NiTe@RuO 2 and NiTe@NiFe-LDH were constructed by coupling ruthenium oxide and nickel−iron layered double hydroxide on T-shaped NiTe. 123 The as-made NiTe@RuO 2 and NiTe@NiFe-LDH catalysts also exhibited an outstanding HER catalytic activity. Among all the catalysts, NiTe@RuO 2 delivered the lowest overpotential of 19 mV at 10 mA cm −2 , much lower than that of RuO 2 (98 mV), NiTe (189 mV), and bare NF (212 mV).…”

Water splitting as an advanced energy conversion technology driven by sustainable energy is attracting ever-increasing attention for clean hydrogen fuel generation from water. Two fundamental reactions, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), are involved, and cost-effective catalysts are required to fulfill the energy transfer process. Nonprecious-metal catalysts have been proposed as the mainstay for future commercial applications. Among them, iron−nickel (FeNi)based catalysts are very promising benefiting from the FeNi synergistic interaction in promoting the basic reactions. With the help of rational structure design, composition optimization, and electronic state tuning, advanced catalysts based on FeNi have been extensively reported. Herein, we focus on the varied FeNi-based catalysts for water splitting reactions. Before reviewing the literature, some descriptors and perspective comments are first given in the parameter evaluation part that might be helpful for understating the catalytic capability. In light of the extensive reports, some typical examples of FeNi-based catalysts classified into FeNi-alloy, phosphides, oxides, layered double hydroxides, sulfides, tellurides, selenides, and fluorides are introduced in detail. Combined with these advanced catalysts and the performance evaluation, this review will be helpful for readers in understanding the advanced progress on FeNi-based catalysts for water splitting reaction. Problems and challenges are also discussed demonstrating that efficient catalysts that can maintain high activity and stability are still highly desired. A brief perspective on FeNi-based catalysts is proposed that we hope can be a good complement to the existing literature for a better understanding of FeNi-based catalysts for water splitting reaction.

Electrochemical water splitting for hydrogen production has sparked intensive interests because it provides a new approach for sustainable energy resources and the avoidance of environmental problems. The precious metal‐based single atomic catalysts (PMSACs) have been widely employed in water splitting catalysis by virtue of their maximum atom utilization and unique electronic structure, which can reduce metal amounts and remain high catalytic performance simultaneously. In this review, we will summarize recent research efforts toward developing SACs based on precious metals with excellent performance for electrochemical water splitting catalysis. First, the synthesis strategies for PMSACs will be classified and introduced including high‐temperature pyrolysis, electrochemical method, photochemical reduction, wet chemistry method, etc. Then, a short description of characterization techniques for SACs will be given, which mainly involves the aberration‐corrected scanning‐transmission electron microscopy (AC‐STEM) and X‐ray absorption spectroscopy (XAS). In particular, the relationship between the electronic structure of the precious metal atomic sites and performance for water splitting will be discussed according to the theoretical and experimental results. Finally, a brief perspective will be provided to highlight the challenges and opportunities for the development of novel PMSACs suitable for electrochemical water splitting applications.

“…Nowadays, due to the rapid increase in environmental hazards and excessive consumption of non-renewable fossil fuels, exploration of clean and sustainable energy sources through unlimited natural resources has become more important. − Hydrogen (H 2 ) as a green and sustainable form of energy with high energy density, abundance, low cost, and environmentally friendly nature (with the only combustion product of water), makes it an ideal form of energy alternative to fossil fuels. − Among the existing technologies for hydrogen generation, the electrocatalytic water splitting has been considered as a highly efficient strategy for transforming the electric energy into chemical fuel, and can easily be combined with other renewable energy sources (i.e., wind and solar). − Water splitting reactions mainly involve hydrogen evolution reaction (HER) (i.e., 2H + + 2e – → H 2 ) and oxygen evolution reaction (OER) (i.e., 2H 2 O → O 2 + 4H + + 4e – ), which generally need high overpotentials, among which OER possesses particular sluggish kinetics . Noble metal nanoparticle-based catalysts, such as platinum (Pt), and ruthenium and iridium oxides (RuO 2 and IrO 2 ), are regarded as excellent HER and OER electrocatalysts .…”

Exploration of highly efficient bifunctional electrocatalysts for optimal hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) has been widely carried out, though it still remains a big challenge. Herein, a hierarchical CoO–Co4N@NiFe-LDH (layered-double-hydroxides) heterostructure electrode anchored on nickel foam (NF) is prepared via a developed three-step hydrothermal–nitridation–electrodeposition pathway. The fabricated CoO–Co4N@NiFe-LDH/NF electrode needs low overpotential values of 66 and 231 mV to supply a current density value of 10 mA cm–2 in aqueous solution of KOH (1 M) for HER and OER, respectively. The Tafel slopes and electrochemical impedance spectroscopy results display favorable reaction kinetics throughout the electrolysis process. Subsequently, an alkaline electrolyzer is assembled with CoO–Co4N@NiFe-LDH/NF, which serves both as the anode and cathode, yielding 10 mA cm–2 with a small voltage of 1.529 V and showing a robust stability for 28 h. Impressively, a urine-mediated electrolysis cell shows efficient catalytic activity as well, allowing to mount the sluggish OER during water splitting. To drive the urine-mediated electrolysis cell containing 0.33 M urea, a low voltage of 1.393 V is required, which is about 136 mV lower compared to the urea-free electrolysis cell. This work presents a solid step for the electrocatalytic generation of hydrogen through water splitting by harvesting low energy.
