“…Moreover, the synthesis of 2D/2D SnNb 2 O 6 /CoFe‐LDH (SNO/LDH) results in an increase in reactant adsorption, with an increase in adsorption amount q e for SNO/LDH being the highest at 44.51 mg g −1 to promote the photocatalytic performance. [ 134 ] This phenomenon is also in concord with another study on Fe 3 O 6 /MgAl‐LDH, where the distribution of small Fe 3 O 4 nanosheets on MgAl‐LDH platelets effectively prevents the overlap of LDH nanosheets as well as increases surface roughness ( Figure a,b), hence enlarging the specific surface area. [ 135 ] Therefore, the promotional effect of the interfacial engineering of 2D/2D heterojunctions can be envisaged to span across different classes of nanomaterials discussed in this section.…”

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.

“…Since the Frank discovered that photocatalytic reaction can oxide CN − to OCN − , photocatalytic technology in the environmental‐protection application has received wide attention of researchers at home and abroad . Profiting from the unique advantages of ultrathin 2D semiconductors, such as a large space for light absorption and photocatalytic reaction and the ultrathin thickness facilitates the rapid transfer of photogenerated carriers to the surface or interface, the 2D semiconductors show great prospect for photodegradation organics . For example, Wang and co‐workers successfully synthesized freestanding monolayer Bi 2 WO 6 with a sandwich substructure of [BiO] + ‐[WO 4 ] 2 ‐[BiO] + by cetyltrimethylammonium bromide (CTAB) assistance (Figure ).…”

The search for highly active photocatalysts remains one of the most challenging tasks for realizing efficient solar energy utilization. Inspired by their unique and excellent physicochemical properties, ultrathin two-dimensional (2D) semiconductors present great advantages in photocatalytic researches. In this review, we summarize the state-of-art progress on the ultrathin 2D semiconductors with a particular emphasis on their recent advances in energy and environment applications. First, we introduce the historical developments of 2D nanomaterials, and outline their advantages in terms of photocatalysis. Second, the classifications of ultrathin 2D semiconductors are summarized based on their structure and compositions. Further, various energy and environment applications including water splitting, CO 2 reduction, N 2 fixation, organic syntheses, NO x removal, water treatment, and sterilization in recent years (mainly in the recent 3 years) are highlighted in detail. Finally, the personal perspectives on future challenges and outlooks in the field of energy and environment applications are featured.[a] Dr.
