Summary: In this study, we developed a hydrothermal sulfurization-acid assisted etching strategy to fabricate Mo doped NiS/Ni3S2 polymorph heterostructure with rich sulfur vacancies (Mo-NiS/Ni3S2-rich Sv). It was discovered that the S centers on the Ni3S2 side of the nickel sulfide polymorphs served as the H2-evolving sites, while the Ni sites on the Mo-NiS side facilitated the cleavage of the HO-H bond. The presence of rich Sv expedited the evolution of H* to molecular H2, leading to enhanced HER kinetics. The optimized Mo-NiS/Ni3S2-rich Sv electrocatalyst exhibited excellent HER activity and durability in alkaline solution. Understanding the synergy of polymorph heterostructure and element defect is crucial for the rational design of high-performance HER electrocatalysts.

Summary: The research on active and efficient electrocatalysts is crucial for the practical application of energy conversion devices. In this study, porous rhodium octahedra were synthesized through a one-pot method called corner-induced-selective-deposition (CISD), and their performances in alkaline media for oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR) were significantly enhanced by interfacial boron modification. The incorporation of boron improved the adsorption properties of the catalyst surface and reduced the overpotentials for the three reactions. This work has the potential to guide the design of other nanoscale functional materials with delicate nanostructures and optimized compositions.

Summary: The introduction of Cl-terminated MXenes-Ti3CNCl2 can significantly reduce the HER potential of CoS2-based materials, leading to higher activity. The Ti3CNCl2@CoS2 core-shell nanostructure achieves a significant enhancement in HER performance through interface-charge transfer between CoS2 and Ti3CNCl2, resulting in a higher degree of electronic localization and chemical bonding.

Summary: A facile methodology was reported for fabricating hierarchical porous nanostructures riveted with ultrafine Ru nanoclusters, serving as high-performance nanoreactors for overall water splitting. The nanoreactors exhibited remarkable performance for hydrogen evolution reaction (HER) across a wide pH range, with an alkaline HER overpotential of only 25 mV@10 mA cm(-2) and an ultrahigh turnover frequency (TOF) value. Additionally, the nanoreactors showed prominent oxygen evolution reaction (OER) activity and were used to construct a two-electrode device for efficient overall water splitting with high H-2 generation rates in varied pH media.
