“…Despite notable advancements in this area, obtaining welldefined structures of these clusters remains a formidable challenge, primarily due to the intricate arrangement of Ag ions within the aggregates and the complicating effect of noncovalent argentophilic interactions during the assembly process [10][11][12][13][14][15][16]. Protective ligands, such as thiols, alkynes, phosphines, or their combinations, play a vital role in Ag NCs assembly [17][18][19][20][21][22][23][24][25]. The utilization of macrocyclic molecules with multiple pre-organized binding sites, despite being infrequently used, offers enhanced efficiency for Ag NCs assembly.…”

The utilization of metalloligands as building blocks for assembling heteronuclear metallocages or heterometallic coordination polymers has garnered increasing attention, yet its utilization for assembling Ag(I) alkynyl nanoclusters remains limited. In this study, we present the synthesis of two new Ag(I) alkynyl nanoclusters, namely, Mo 2 Ag 8 and Mo 2 Ag 12 , employing a Mo VI O 2 R-anchored (R = O or OEt) thiacalix[4]arene (TC4A) as a metalloligand. Through detailed structural analyses, their distinct sandwich geometries were revealed. Mo 2 Ag 8 features a square Ag 4 ( t BuC≡C) 4 core enclosed between two {MoAg 2 -TC4A} units, with two MoO 2 (OEt) units suspended on each side. Mo 2 Ag 12 features a hexagonal Ag 6 ( t BuC≡C) 6 core sandwiched between two {MoAg 3 -TC4A} units, with two MO 3 units acting as oxygen anion templates, directly interacting with Ag(I) ions. In addition, we demonstrated the electrocatalytic application of Ag-Mo bimetallic clusters for CO 2 reduction. The catalytic analysis results show that the binding mode of MO 3 units considerably influences the electrochemical CO 2 reduction activity and competitive hydrogen evolution reaction activity of the clusters. Notably, Mo 2 Ag 12 achieved an impressive Faradaic efficiency of 60.85% for CO production at a voltage of −0.8 V (vs. RHE).

In this study, 3-dimensional molybdenum disulfide (MoS2) structures, integrated with hematite (α-Fe2O3) nanoparticles, were fabricated under a convenient two-step hydrothermal route. The fabricated photocatalytic nanocomposites consist of well-arranged MoS2 flakes, resembling spherical flower-like morphology, and the nanoparticulate α-Fe2O3 structures decorate the 3D network. By raising the α-Fe2O3 weight ratio, the composites’ specific surface area and morphology were not affected, regardless of the partial cover of the cavities for higher hematite content. Moreover, the crystallinity examination with XRD, Raman, and FTIR techniques revealed that the precursor reagents were fully transformed to well-crystalized MoS2 and Fe2O3 composites of high purity, as no organic or inorganic residues could be detected. The photocatalytic oxidation and reduction performance of these composites was evaluated against the tetracycline pharmaceutical and the industrial pollutant hexavalent chromium, respectively. The improvement in the removal efficiencies demonstrates that the superior photoactivity originates from the high crystallinity and homogeneity of the composite, in combination with the enhanced charge carriers’ separation in the semiconductors’ interface.

Engineering advanced therapeutic and diagnostic nano‐bio‐platforms (NBPFs) have emerged as rapidly‐developed pathways against a wide range of challenges in antitumor, antipathogen, tissue regeneration, bioimaging, and biosensing applications. Emerged 2D materials have attracted extensive scientific interest as fundamental building blocks or nanostructures among material scientists, chemists, biologists, and doctors due to their advantageous physicochemical and biological properties. This timely review provides a comprehensive summary of creating advanced NBPFs via emerging 2D materials (2D‐NBPFs) with unique insights into the corresponding molecularly restructured microenvironments and biofunctionalities. First, it is focused on an up‐to‐date overview of the synthetic strategies for designing 2D‐NBPFs with a cross‐comparison of their advantages and disadvantages. After that, the recent key achievements are summarized in tuning the biofunctionalities of 2D‐NBPFs via molecularly programmed microenvironments, including physiological stability, biocompatibility, bio‐adhesiveness, specific binding to pathogens, broad‐spectrum pathogen inhibitors, stimuli‐responsive systems, and enzyme‐mimetics. Moreover, the representative therapeutic and diagnostic applications of 2D‐NBPFs are also discussed with detailed disclosure of their critical design principles and parameters. Finally, current challenges and future research directions are also discussed. Overall, this review will provide cutting‐edge and multidisciplinary guidance for accelerating future developments and therapeutic/diagnostic applications of 2D‐NBPFs.
