“…Because the bonding energy of noble metals with H was weaker than that of Ru, the strong adsorption energy of H on the Ru surface can be tuned to increase the hydrogen evolution performance . The Ru-related noble metal alloy catalysts, such as PtRu, , RhRu, PdRu, , IrRu, − AuRu, etc., have been developed recently. The alloyed RuPt nanoparticles can reduce the amount of necessary Pt and retain the enhanced catalytic activity of Pt .…”

“…For example, the RuPd alloy nanoparticles anchored on Ndoped porous carbon dodecahedron (Ru x Pd 1−x @NPC) were obtained by microwaves assisting the glycol reduction method (Figure 9a). 127 When full advantage of the control of components and the synergism between metals is taken, only a relatively low content of the noble metal alloy was required to synthesize the catalyst, where Ru 0.7 Pd 0.3 @NPC showed enhanced alkaline HER activity with the overpotential of only 20 mV for 10 mA cm −2 . Meanwhile, Ru 0.3 Pd 0.7 @NPC delivered an overpotential of 36 mV to reach 10 mA cm −2 in acidic media.…”

The water-splitting reaction for green hydrogen generation requires highly efficient catalysts on the side for the hydrogen evolution reaction (HER), and metal ruthenium (Ru) is considered a promising catalyst as a result of its similar property in hydrogen-bonding ability but low cost compared to Pt-based materials. The performance is further boosted by the recently developed hybrid Ru-based electrocatalysts. To reveal the relationship between the hybrid catalyst systems and activity for Ru-based catalysts, the research progress of heterostructured Ru hybrid catalysts in the HER is reviewed in this effort. The enhancement of HER activity of Ru hybrid catalysts is first described on the basis of the synergistic effect, strain effect, and electronic effect, and then, the latest progress is discussed in three categories of single ruthenium catalysts, ruthenium-related compounds, and ruthenium alloy catalysts. It is concluded that the heterostructured interface engineering strategy plays an important role in enhancing the activity of Ru-based catalysts in the HER. In the end, the actual problems and challenges are discussed, e.g., the intrinsic activity and stability, application in the real device, etc. It is recommended to pay attention to the long-term stability, performance, and structural evolution as well as the application of the catalysts in the devices. It is hoped that this effort will help with understanding the progress of Ru-based hybrid catalysts in the field of HER catalysis.

The proactive exploration of electrocatalytic conversion for renewable energy valorization is of tremendous significance in addressing the issues of fossil energy exhaustion, among which the critical challenge of electrocatalysis lies in the rational design of efficient electrocatalysts that are rich in the earth. Among electrocatalysts, the design of heterostructured materials exhibits immense potential for the optimization of noble metals and elaboration of non‐precious metal electrocatalysts with durability. In this review, a systematic overview of modern advances in heterostructured electrocatalysts for a range of energy conversion reactions is described, and special interfacial design brings additional functional effects. Subsequently, various synthesis methods and characterization techniques for heterostructured electrocatalysts are also summarized. The innovative classification of heterostructures in methods of interfacial junction, crystal structure, structural morphology, and properties of the components is presented in this review. Finally, the possible challenges and outlooks of heterostructured electrocatalysts in the future are further discussed, including how to develop more sophisticated synthesis, characterization, and theoretical calculation methods, which will serve as the guiding direction for a more rational interface design. This review aims to set the trajectory for providing meaningful inspiration and references in energy conversion by heterostructured electrocatalysts, advancing the process of carbon neutrality.
