Summary: In this study, a Co-introduced fine-modulated NiFe-LDH performance strategy was proposed and successfully used to construct Co-doped NiFe-LDH nanosheets arrays. The optimized nanosheets showed low overpotentials and an extremely low Tafel slope. The stability test proved the good stability of the nanosheets even at high current densities. The theoretical calculation was consistent with the experimental verification, providing a simple and effective method for designing and constructing efficient water oxidation catalysts.

Summary: In this study, a series of M-doped Co3O4 materials were grown on a Ni foam substrate, and it was found that doping with Ce significantly enhanced the water and urea oxidation performance, while doping with Ni and Fe reduced the performance. The experimental results suggest that the improved activity of the Ce-doped electrode can be attributed to faster electron transport capacity, higher exposure to active sites, and improved conductivity. This work provides a new approach to enhance the electrocatalytic activity of catalysts through doping strategy.

Summary: Multifunctional electrocatalysts with excellent performance are highly desirable for new energy technologies. An electrocatalyst is synthesized using a straightforward two-step approach, whereby ultralow doping (0.06 wt%, Fe) and a heteroatom (N) generate defects. The defect-induced active sites and porous channels enable high catalytic activity and durability for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER).

Summary: The tungsten-doped Ni-Fe hydroxides fabricated through cathodic electrodeposition on three-dimensional nickel foam are proposed as efficient catalysts for alkaline water oxidation. Incorporating an appropriate amount of tungsten into the hydroxides modulates the electronic structure, creating abundant active sites for the oxygen evolution reaction. The optimized electrocatalyst outperforms the traditional 20 wt% Ir/C catalyst, requiring small overpotentials for generating current densities at extremely low Tafel slope, with tungsten dopant stabilizing the active sites for water oxidation.

Summary: The bottleneck of large-scale implementation of electrocatalytic water-splitting technology is the lack of inexpensive, efficient, and durable catalysts for accelerating the sluggish oxygen evolution reaction kinetics. This study reports the activation and stabilization of cobalt telluride (CoTe) nanoarrays for the oxygen evolution reaction (OER) through dual integration of sulfur (S) doping and surface oxidization. The synthesized CoO@S-CoTe catalyst exhibits superior OER performance compared to commercial RuO2 and other reported telluride-based OER catalysts, with a low overpotential and long-term stability.

Summary: Highly performing non-metal inexpensive electrocatalysts are needed for hydrogen production. Carbon dots (CDs) with large specific surface area, low cost, high conductivity, and rich functional groups, as well as conductive substrates, show promise as non-metal electrocatalysts. In this study, a unique 3D superstructure of carbon nanohorns (CNHs) is used as a conductive support for CDs, promoting charge transfer and accelerating hydrogen evolution. The all-carbon non-metal CDs/CNHs nanoensemble exhibits similar performance to Pt/C in onset potential, low charge transfer resistance, and excellent stability.
