“…Balance and optimize the activity and stability of TM LDH nanosheets is also a challenge. [ 120 ] Strategies to elaborately tune the electronic structure and increase the active atoms exposure might be able to address this issue, like topotactic transformation. Recently, topotactically transformed polygonal mesoporous TM LDHs, mediated via metal‐organic framework, exposed abundant under‐coordinated metal centers that lowered the energy barrier of OER and HER.…”

Nowadays, to alleviate the growing pressure of energy shortages and environmental pollution, electrochemical energy conversion is seen as a fossil‐free, secondary pollution‐free, and highly efficiency pathway. Electrocatalysts, as the “heart” of the electrochemical conversion process, play a key role in accelerating reaction rates and promoting efficiency. Transition‐metal‐based layered double hydroxides (TM LDHs), one of the famous electrocatalysts, show unique 2D supermolecular‐stratified structure, excellent electronic properties, and their raw materials are easily available. In this review, electrocatalysis‐related properties of TM LDHs and the state‐of‐the‐art synthesis methods of TM LDH‐based electrocatalysts are summarized. Modifications for promoting the development of TM LDH‐based electrocatalysts are included, such as carbon materials modification, defect engineering, and noble metal loading. Then, the application of TM LDH nanosheets in the field of electrocatalysis is reviewed in detail. Finally, recent challenges, ongoing improvements, and future expectations for TM LDH nanosheets are presented.

Layered double hydroxide (LDH) is a class of 2D nanomaterials, which endows auspicious properties for ameliorating the photocatalytic performance in the realm of solar‐to‐chemical production stemming from the chemical versatility of their host layers. However, pristine LDH suffers from slow charge‐carrier mobility, high rate of electron–hole recombination as well as a tendency to agglomerate, rendering them unbefitting for practical use. Due to the aforementioned bottlenecks, structural modifications such as thickness tuning, cocatalyst incorporation, semiconductor coupling, and ternary heterostructure engineering have been extensively investigated to elucidate a new lease of landscape to the burgeoning potential of LDHs toward artificial photosynthesis. This review summarizes a panorama of state‐of‐the‐art advancements related to the synthesis and modification of LDH‐based nanocomposites for enhanced physicochemical properties toward boosted photocatalysis. Particularly, their progress in versatile energy applications in photocatalytic water splitting (hydrogen and oxygen evolution), and nitrogen and carbon dioxide reduction reactions will be systematically presented. Insights into band structures, electronic properties, and charge‐carrier dynamics of LDH‐based nanostructures will be discussed to unravel the structure–performance relationship. Finally, this review will prospect the invigorating prospectives and opportunities in engineering next‐generation LDH‐based photocatalysts with augmented performances to pave new inroads at the forefront of this research.
