“…This effect contributed to the enhancement of HER performance. Furthermore, Sun et al [44] loaded different-sized Ru catalysts (single atoms, nanoclusters, and nanoparticles) on N-doped carbon (NC) [45] support (Figure 3c), preparing a pH-universal Ru-based electrocatalyst. Among these catalysts, Ru nanocluster catalysts (Ru NCs/NC) exhibited the best catalytic performance, with overpotentials of only 14, 30, and 32 mV (at a current density of 10 mA cm −2 ) in 1.0 M KOH, 1.0 M phosphate-buffered saline (PBS), and 0.5 M H 2 SO4, respectively.…”

Hydrogen has emerged as an important candidate for clean energy, owing to its environmentally friendly advantages. Electrolytic hydrogen production stands out as the most promising technology for hydrogen production. Therefore, the design of highly efficient electrocatalysts is significant to drive the application of hydrogen technologies. Platinum (Pt)-based catalysts are famous for their outstanding performance in the hydrogen evolution reaction (HER). However, the expensive cost limits its wide application. Ruthenium (Ru)-based catalysts have received extensive attention due to their relatively lower cost and HER performance similar to that of Pt. Nevertheless, the performance of Ru-based catalysts is still unable to meet industrial demands. Therefore, improving HER performance through the modification of Ru-based catalysts remains significant. In this review, the reaction mechanism of HER is analyzed and the latest research progress in the modification of Ru-based electrocatalysts is summarized. From the reaction mechanism perspective, addressing the adsorption of intermediates on the Ru-based electrocatalyst surface, the adsorption–activation of interface water molecules, and the behavior of interface water molecules and proposing solutions to enhance performance of Ru-based electrocatalyst are the main findings, ultimately contributing to promoting their application in the field of electrocatalysis.

“…5,6,13,14 The introduction of nitrogen (N) donor ligands, which coordinate to Ru, is a means to stabilize the NPs against aggregation as well as to tune the local chemical environment, thereby facilitating the desorption of hydrogen. 5,[13][14][15] The introduction of other heteroatoms, particularly sulfur (S), could have similar effects for additional netuning the electrocatalytic performance. 5,6,[16][17][18] The efficiency of the HER reaction also strongly depends on the nature of the electrolyte, which essentially affects the reaction mechanism (Table 1).…”

“…The early transition metal oxides, such as Nb 21 and Ti, , which exhibit limited redox activity, demonstrate weak substrate-induced enhancement in performance. Theoretically, the nanocluster catalysts supported by oxide substrates with redox activity are expected to maintain excellent dispersion of nanoclusters and achieve high catalytic activity by modulating the electronic structure of active sites via metal–support interactions. , However, the redox-active oxides of Fe, Co, and Ni are not suitable for acidic OER due to their lack of acid resistance. − Notably, manganese dioxide (MnO 2 ) has been considered as one of the most promising substrates and widely studied in OER catalysis, owing to its unique properties, including the rich variation of Mn valence, high acid resistance, abundant crystal phases, and excellent adsorptive abilities. − …”

Noble metal-based electrocatalysts are crucial for efficient acidic water oxidation to develop green hydrogen energy. However, traditional noble metal catalysts loaded on inactive substrates show limited intrinsic catalytic activity, and their large sizes have compromised the atom efficiency of these noble metals. Herein, IrO x nanoclusters with sizes below 2 nm, displaying high atom-utilization efficiency of Ir species, were supported on a redox-active MnO 2 nanosubstrate (IrO x /MnO 2 ) with different phases (α-MnO 2 , δ-MnO 2 , and ε-MnO 2 ) to explore the optimal combination. Electrochemical measurements showed that IrO x /ε-MnO 2 had excellent OER performance with a low overpotential of 225 mV at 10 mA cm −2 in 0.5 M H 2 SO 4 , superior to its counterpart, IrO x /α-MnO 2 (242 mV) and IrO x /δ-MnO 2 (286 mV). Moreover, it also delivered robust stability with no obvious change in operating potential at 10 mA cm −2 during 50 h of continuous operation. Combining the XPS results and Bader charge analysis, we demonstrated that the strong metal−support interactions of IrO x /ε-MnO 2 could effectively regulate the electronic structures of the active Ir atoms and stabilize IrO x nanoclusters on supports to suppress their detachment, resulting in significantly enhanced catalytic activity and stability for acidic OER. DFT calculations further supported that the enhanced catalytic OER performance of IrO x /ε-MnO 2 could be ascribed to the appropriate strength of interactions between the active Ir sites and the reaction intermediates of the potential-determining step (*O and *OOH) regulated by the redox-active substrates.
