“…Electrochemical water splitting is appearing as one of the most promising strategies for producing green and clean hydrogen. [119,120] Electrochemical water splitting involves two central half reactions, namely anodic oxygen evolution reaction (OER) and cathodic hydrogen evolution reaction (HER), in which the theoretically thermodynamic potential of 1.23 V is required. The anodic OER is a process of the electrochemical water splitting that produces oxygen in both acid (2H 2 O(l)!O 2 (g) + 4H + + 4e À ) and alkaline (4OH À !…”

Low‐dimensional high‐entropy alloy (HEA) nanomaterials are widely employed as electrocatalysts for energy conversion reactions, due to their inherent advantages, including high electron mobility, rich catalytically active site, optimal electronic structure. Moreover, the high‐entropy, lattice distortion, and sluggish diffusion effects also enable them to be promising electrocatalysts. A thorough understanding on the structure‐activity relationships of low‐dimensional HEA catalyst play a huge role in the future pursuit of more efficient electrocatalysts. In this review, we summarize the recent progress of low‐dimensional HEA nanomaterials for efficient catalytic energy conversion. By systematically discussing the fundamentals of HEA and properties of low‐dimensional nanostructures, we highlight the advantages of low‐dimensional HEAs. Subsequently, we also present many low‐dimensional HEA catalysts for electrocatalytic reactions, aiming to gain a better understanding on the structure‐activity relationship. Finally, a series of upcoming challenges and issues are also thoroughly proposed as well as their future directions.

“…Transition metal sulfides (TMSs) are also a category of promising electrocatalysts for energy conversion because of their environmental compatibility, rich structural diversity, low cost, and wide availability. [108][109][110][111] By taking the inherent advantages of TMSs and structural features, constructing TMSs-based hollow heterostructures will benefit for the further promotion of catalytic performance. Lou et al [112] synthesized the hierarchical tubular heterostructures by in-situ growing 2D ZnIn 2 S 4 nanosheets onto the 1D hollow Co 9 S 8 nanotubes.…”

The implementation of electrochemical water splitting demands the development and application of electrocatalysts to overcome sluggish reaction kinetics of hydrogen/oxygen evolution reaction (HER/OER). Hollow nanostructures, particularly for hollow heterostructured nanomaterials can provide multiple solutions to accelerate the HER/OER kinetics owing to their advantageous merit. Herein, the recent advances of hollow heterostructured nanocatalysts and their excellent performance for water splitting are systematically summarized. Starting by illustrating the intrinsically advantageous features of hollow heterostructures, achievements in engineering hollow heterostructured electrocatalysts are also highlighted with the focus on structural design, interfacial engineering, composition regulation, and catalytic evaluation. Finally, some perspective insights and future challenges of hollow heterostructured nanocatalysts for electrocatalytic water splitting are also discussed.

“…The OER is also a significant half reaction for many important energy conversion technologies, such as metal-air batteries and water electrolysis. [66][67][68] For electrocatalytic water splitting, the OER is commonly considered as the key issue to determine the overall efficiency due to the kinetically sluggish process, which involves a four proton-coupled electron transfer process. [69][70][71] To accelerate the reaction kinetics and improve the OER efficiency, appropriate electrocatalysts should be introduced.…”
