“…Therefore, the Mo atoms at the S vacancies were exposed, which could function as the coordination centers to bond with ligands, as shown in Figure a. With this strategy, various kinds of building blocks that involved sulfur‐, oxygen‐, nitrogen‐containing functional groups were employed as ligands to coordinate with MoS 2 through S vacancies, resulting in multifunctional hybrid nanostructures …”

“…After hybridization with molecules that had thiol, disulfide, oxygen, or nitrogen containing functional groups, the resulting molecules‐MoS 2 hybrid nanostructures showed not only improved processibility, but also new functions and properties. Moreover, the molecular building blocks could also provide reactive functional groups that laid a basis to assemble with another building block, resulting in multicomponent hybrid nanostructures . For instance, Zhou and co‐workers reported a ternary hybrid nanostructure based on MoS 2 via a three‐step strategy (Figure e) .…”

nanobelts), 2D materials exhibit exceptional physical properties including large theoretical surface area, tunable electronic properties, high optical transparency, and excellent mechanical properties. [2] However, the strong re-stacking tendency of 2D materials caused by van der Waals interaction may result in serious loss of surface area, which inevitably weakens their unique properties. Besides, 2D materials always show intrinsic deficiencies for specific applications, despite the merits mentioned above. As a typical example, TMDs possess high theoretical specific capacities for lithium-ion storage but exhibit unsatisfied cyclability and rate capability in practice, because of their aggregation, low conductivity as well as huge volume expansion during lithium-ion insertion/extraction. [3] One effective way to solve these problems is to construct hybrid nanostructures based on 2D materials. [4][5][6][7][8] Hybrid nanostructures, as a class of composite materials, are composed of two or more nanostructured building blocks. [9,10] Hybrid nanostructures not only can energetically combine the intriguing merits and overwhelm the deficiencies of each building block, but also may generate new functions and properties. [3][4][5][6][7][8][11][12][13] These advantages make hybrid nanostructures based on 2D materials highly promising for practical applications with high performance. [14][15][16][17][18] Regarding the multicomponent composition of hybrid nanostructures, the interfacial interaction between the building blocks lays the foundation for structural and morphological stability, thereby influencing the functions and properties of the resulting hybrid nanostructures. [19][20][21][22] In this sense, the rational design and construction of reliable interfacial interaction for hybrid nanostructures are not only important for achieving improved performance, but also critical for understanding the fundamentals of structureproperty relationship.Generally, there are five types of interfacial interactions, i.e., covalent bond, coordination bond, hydrogen bond, π-π interaction, and electrostatic interaction. [19][20][21][22] Covalent bond and coordination bond are much stronger than the other three in terms of bond energy, so the former two are more favorable for constructing hybrid nanostructures with reliable interfacial interaction. [19] However, most 2D materials are chemically inert, which means the covalent modification is not suitable for them. Alternatively, there are coordination atoms in most of 2D materials and their derivatives, and hence coordination 2D materials have received tremendous scientific and engineering interest due to their remarkable properties and broad-ranging applications such as energy storage and conversion, catalysis, biomedicine, electronics, and so forth. To further enhance their performance and endow them with new functions, 2D materials are proposed to hybridize with other nanostructured building blocks, resulting in hybrid nanostructures with various morphologies and structures.

“…Consequently, numerous efforts have been devoted to get rid of 4-NP by reducing it to 4-AP. Several methods have been employed to resolve this issue such as electrochemical treatment, photocatalytic degradation, microbial degradation and catalytic reduction [ 17 , 18 ]. It has been observed that reductive catalysis is an effective way to degrade 4-NP [ 19 – 21 ].…”

Background Anthranilic acid is an active compound with diverse biological activities such as anti-inflammatory, antineoplastic, anti-malarial and α-glucosidase inhibitory properties. It can also chelate transition metals to form complexes with applications as antipathogens, photoluminescent materials, corrosion inhibitors, and catalysts. Results Anthranilic acid complexes (1–10) of Zn(II), Bi(III), Ag(I), Fe(II), Co(II), Cu(II), Mn(II), Al, Ni(II), and Cr(III) were synthesized and characterized using thermogravimetric (TGA), elemental analysis, FT-IR, UV–vis spectrometry, mass spectrometry and magnetic susceptibility. The morphology and size of metal complex (1–10) particles were determined by scanning electron microscope (SEM) and the surface area was determined by BET analysis. TGA and CHN analysis data indicated that the stoichiometries of complexes were 1:2 metal/ligand except for Ag(I), Al and Bi. Furthermore, DFT study was performed to optimize the structure of selected complexes. The complexes (1–10) were evaluated for their catalytic activity in the reduction of 4-nitrophenol (4-NP), antibacterial activity against S. aureus, P. aeroginosa and E. coli as well as their antifungal activity against F. solani and A. niger. The complexes were also tested against the second-stage juveniles (J2) root-knot nematodes. Conclusion Co(II) complex 5 and Cu(II) complex 6 showed high catalytic activity for the reduction of 4-NP to 4-aminophenol (4-AP). Ag(I) complex 3 showed the best activity against the pathogens that were tested namely clinically important bacteria S. aureus, P. aeroginosa and E. coli, commercially important fungi F. solani and A. niger and J2 root-knot nematodes M. javanica.

“…Therefore, how to effectively and completely degrade the pollutant has become a hot issue [5,6]. Traditional physical methods such as adsorption, deposition and filtration cannot fundamentally treat the pollution of PNP [7][8][9]. Biodegradation not only has little effect, but also may cause the later energy and cost burden [10,11].…”

Flexible and hierarchical nanostructured Pd/SiO 2 -TiO 2 nanofibrous catalytic membranes were fabricated via combining electrospinning technique and a two-step hydrothermal method. The size and distribution of TiO 2 nanorods immobilised on SiO 2 nanofibrous membranes can be regulated via adjusting the dosage of TiCl 3 solution in the first step hydrothermal process. When using an optimal TiCl 3 solution dosage of 0.2 mL, a hierarchical structured Pd/SiO 2 -TiO 2 -0.2 nanofibrous catalytic membrane with uniformly dense TiO 2 nanorods loaded on SiO 2 nanofibers is obtained, and still shows good tensile strength and flexibility. The catalytic activity of Pd/SiO 2 -TiO 2 -0.2 increases 5 times as compared to Pd/SiO 2 -TiO 2 -0 in the reduction of p-nitrophenol (PNP) to p-aminophenol (PAP). The modification with TiO 2 nanorods can provide more surface areas for loading the Pd nanoparticles, thereby increased active sites. The three-dimensional open-cell network stacked and assembled by thousands of SiO 2 nanofibers and TiO 2 nanorods enhances the contact between the reactants and Pd nanoparticles. Both aspects contribute the superior catalytic activity of Pd/SiO 2 -TiO 2 -0.2. Furthermore, a continuous and complete conversion of PNP to PAP can be stably operated over 240 min in a gravity-driven catalytic membrane reactor constructed by Pd/SiO 2 -TiO 2 -0.2.
