Here, we report the synthesis, characterization, and properties of novel nanohybrids formed by self-assembly negatively charged MoS2 nanoplates positively iron oxide nanoparticles (NPs) two different sizes, 5.1 11.6 nm. Iron NPs were functionalized with an amphiphilic random copolymer, quaternized poly(2-(dimethylamino)ethyl metacrylate-co-stearyl metacrylate), synthesized for first time using atom transfer radical polymerization. The influence fraction NP size on structure has been studied....
The product of exfoliation and restacking MoS2 in acidic conditions is studied detail using X-ray powder diffraction, transmission electron microscopy (TEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC). temperature dependence patterns reveals that the heating exfoliated-restacked a way to new nanostructured MoS2-based layered material remains nanosized even upon 850 °C. Previously this has been described as 2H-MoS2, but according diffraction (XRD) data, its...
Chemical methods for the exfoliation of transition metal dichalcogenides in a liquid medium to give single-layer dispersions containing quasi-two-dimensional layers these compounds are surveyed. Data on structure and their use synthesis various types heterolayered intercalation discussed described systematically. Structural features, electronic physicochemical properties resulting considered. The potential this method is compared with that traditional solid-state layered crystals....
We report a facile, room-temperature assembly of MoS2-based hetero-layered nanocrystals (NCs) containing embedded monolayers imidazolium (Im), 1-butyl-3-methylimidazolium (BuMeIm), 2-phenylimidazolium, and 2-methylbenzimidazolium molecules. The NCs are readily formed in water solutions by self-organization the negatively charged, chemically exfoliated 0.6 nm thick MoS2 sheets corresponding cationic imidazole moieties. As evidenced transmission electron microscopy, obtained anisotropic shape,...
New hybrid materials based on Ag nanoparticles stabilized by a polyaminopropylalkoxysiloxane hyperbranched polymer matrix were prepared. The synthesized in 2-propanol metal vapor synthesis (MVS) and incorporated into the using metal-containing organosol. MVS is interaction of extremely reactive atomic metals formed evaporation high vacuum (10-4-10-5 Torr) with organic substances during their co-condensation cooled walls reaction vessel. Polyaminopropylsiloxanes molecular architectures...
Sustained interest in the use of renewable resources for production medical materials has stimulated research on bacterial cellulose (BC) and nanocomposites based it. New Ag-containing were obtained by modifying various forms BC with Ag nanoparticles prepared metal–vapor synthesis (MVS). Bacterial was form films (BCF) spherical beads (SBCB) Gluconacetobacter hansenii GH-1/2008 strain under static dynamic conditions. The synthesized 2-propanol incorporated into polymer matrix using...
We report the synthesis, structure determination, and quantum-chemical analysis of a new family layered nanocrystals (NCs) obtained by liquid-phase assembly reaction exfoliated, negatively charged MoS2 sheets with alkyldiammonium ions. A combined PXRD, TEM, FTIR DFT study allowed us to determine atomic these turbostratically disordered NCs reveal topology cation-MoS2 binding interactions. The diamine molecules sandwiched between sulfur layers adjacent 1T-MoS2 were found interlink through...
The three-dimensional atomic structure of MoS<sub>2</sub>–organic layered systems is obtained for the first time, providing insight into surface chemistry charged MoS<sub>2</sub> sheets.
Negatively charged molybdenum disulfide layers form stable organic–inorganic layered nanocrystals when reacted with organic cations in solution. The reasons why this self-assembly process leads to a single-phase compound well-defined interlayer distance given conditions are, however, poorly understood date. Here, for the first time, we quantify interactions determining cation packing and stability of MoS2–organic find that main contribution arises from Coulomb forces. study was performed on...
Abstract Metastable modification of MoS 2 (1T) is widely recognized as a hopeful non‐precious electrocatalyst in hydrogen production. This paper describes an approach to impart superambient temperature stability 1T‐MoS by incorporating it 2D hybrid architecture with cationic monomolecular phenanthrolinium (PhenH + ) hydrate layers. The atomic structure and bonding interactions the assembled revealed PXRD, TEM, XPS, Raman UV‐Vis spectroscopy data coupled DFT calculations quantum theory atoms...
Intercalation compounds of MoS 2 with monomeric or OH-bridged dimeric ruthenium arene cationic complexes have been obtained by interaction single-layer dispersions aqueous solutions [(arene)Ru(H O) 3 ]SO 4 [arene=C 6 H , C Me -1,2,4,5, Me-1-Pr i -4]. The structural arrangement these intercalation is discussed on the basis XRD and EXAFS data. ligands are orientated roughly perpendicular to slabs. Their nature determines interlayer spacing as well intercalated cation content. Heating removes...
