Ru‐based materials hold great promise for substituting Pt as potential electrocatalysts toward water electrolysis. Significant progress is made in the fabrication of advanced Ru‐based electrocatalysts, but an in‐depth understanding of the engineering methods and induced effects is still in their early stage. Herein, we organize a review that focusing on the engineering strategies toward the substantial improvement in electrocatalytic OER and HER performance of Ru‐based catalysts, including geometric structure, interface, phase, electronic structure, size, and multicomponent engineering. Subsequently, the induced enhancement in catalytic performance by these engineering strategies are also elucidated. Furthermore, some representative Ru‐based electrocatalysts for the electrocatalytic HER and OER applications are also well presented. Finally, the challenges and prospects are also elaborated for the future synthesis of more effective Ru‐based catalysts and boost their future application.

“…This implies that the development of a heterointerface increases electronic conductivity, boosting charge transport in the electrocatalytic HER process. [ 34 ] In addition, the projected‐density of states (pDOS) diagram of metallic Pt, NiTe‐Ns, and Pt Ns /NiTe‐Ns show that the total DOS of NiTe‐Ns near the Fermi level is contributed to the Ni 3d orbital, while the total DOS of Pt Ns /NiTe‐Ns catalyst is mainly contributed by the hybridization of Ni 3d and Pt 5d orbitals (Figure S23, Supporting Information). [ 21 ] This d‐orbitals hybridization can endow the coupling interface with strong electronic interactions, thereby providing a large number of charge transfer channels to shorten the electronic migration path.…”

Exploring highly efficient hydrogen evolution reaction (HER) electrocatalysts for large‐scale water electrolysis in the full potential of hydrogen (pH) range is highly desirable, but it remains a significant challenge. Herein, a simple pathway is proposed to synthesize a hybrid electrocatalyst by decorating small metallic platinum (Pt) nanosheets on a large nickel telluride nanosheet (termed as PtNs/NiTe‐Ns). The as‐prepared PtNs/NiTe‐Ns catalyst only requires overpotentials of 72, 162, and 65 mV to reach a high current density of 200 mA cm−2 in alkaline, neutral and acidic conditions, respectively. Theoretical calculations reveal that the combination of metallic Pt and NiTe‐Ns subtly modulates the electronic redistribution at their interface, improves the charge‐transfer kinetics, and enhances the performance of Ni active sites. The synergy between the Pt site and activated Ni site near the interface in PtNs/NiTe‐Ns promotes the sluggish water‐dissociation kinetics and optimizes the subsequent oxyhydrogen/hydrogen intermediates (OH*/H*) adsorption, accelerating the HER process. Additionally, the superhydrophilicity and superaerophobicity of PtNs/NiTe‐Ns facilitate the mass transfer process and ensure the rapid desorption of generated bubbles, significantly enhancing overall alkaline water/saline water/seawater electrolysis catalytic activity and stability.

“…9,10 Even though ever-increasing effort has recently been devoted to developing non-PGM-based catalysts, the low activity and poor stability of non-PGM catalysts still cannot satisfy the quest for AEMFCs. 11,12 Thus, there is still an urgent need to develop platinum-free HOR electrocatalysts with both high activity and durability.…”
