The synergetic effect of acid and nickel sites on bifunctional MWW zeolite catalysts for ethylene oligomerization and aromatization

Corresponding H- and Ni-form MWW zeolites were synthesized and compared to investigate the influences of the acidity strength and the synergetic effect of bifunctional sites on the catalytic performance for ethylene oligomerization and aromatization. The acidities of ERB-1 and MCM-22 zeolites with an MWW structure were adjusted via deboronation and desilication to synthesize MCM-56 and ITQ-1. The physicochemical properties of the catalysts were measured via XRD, EDS, EPMA, N-2 sorption, SEM, FT-IR, pyridine adsorption FT-IR, NH3-TPD, XPS and H-2-TPR studies. The effects of the acid strength and Ni/acid site ratio on the product distribution were studied at 523 and 723 K, which are two typical optimal reaction temperatures for oligomerization and aromatization, respectively. According to the characterization and catalytic performance results from this series of catalyst zeolites with similar structures and different acid sites, a fundamental mechanism involving different elementary steps for ethylene oligomerization and aromatization was proposed to explain the synergetic effect of acid and Ni sites on bifunctional MWW zeolites. The synergetic effect impact relating to different acid strength MWW zeolite structures shows that Ni ions on weak acidity zeolites are superior for ethylene conversion and determine the Anderson-Schultz-Flory product distribution at 523 K, and strong acid sites on MCM-22 are preponderant for ethylene conversion and dominate the product distribution at 723 K. Ni species are not only favorable for the dimerization of alpha-olefins at 523 K, but also for dehydrogenation, leading to the generation of aromatics at 723 K. Increasing zeolite acidity strength produces an obviously positive effect on the production of aromatics.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 88150-62-3 is helpful to your research. Quality Control of Phthaloylamlodipine.

The impacts of nitrogen doping on the electrochemical hydrogen storage in a carbon

Activated carbon materials doped with different nitrogen contents and nitrogen functional groups were synthesized. Nitrogen doping can improve the electrochemical hydrogen storage activity as well as the hydrophilicity of the carbon materials. Synthesized with the optimal synthesis conditions, the N-doped activate carbon demonstrated the hydrogen storage capacity of 148.4 mAh g(-1) under 100 mA g(-1) rate, and 84.3% capacity retention at a high current density of 1000 mA g(-1). 73.4% hydrogen could be preserved after a 24 hours rest at open potential. The main nitrogen functional groups on this carbon material were found to be pyrrole N, pyridine N oxide and nitro N. The density functional theory (DFT) calculations revealed that the H adsorption energy on pyridine N and pyrrole N was larger than that of pyridine N, while graphite N had no advantage in improving the H adsorption energy of carbon materials.

Direct C-13 Hyperpolarization of C-13-Acetate by MicroTesla NMR Signal Amplification by Reversible Exchange (SABRE)

Herein, we demonstrate direct C-13 hyperpolarization of C-13-acetate via signal amplification by reversible exchange (SABRE). The standard SABRE homogeneous catalyst [Ir-IMes; [IrCl(COD)(IMes)], (IMes=1,3-bis(2,4,6-trimethylphenyl), imidazole-2-ylidene; COD=cyclooctadiene)] was first activated in the presence of an auxiliary substrate (pyridine) in alcohol. Following addition of sodium 1-C-13-acetate, parahydrogen bubbling within a microtesla magnetic field (i.e. under conditions of SABRE in shield enables alignment transfer to heteronuclei, SABRE-SHEATH) resulted in positive enhancements of up to approximate to 100-fold in the (CNMR)-C-13 signal compared to thermal equilibrium at 9.4T. The present results are consistent with a mechanism of direct transfer of spin order from parahydrogen to C-13 spins of acetate weakly bound to the catalyst, under conditions of fast exchange with respect to the C-13 acetate resonance, but we find that relaxation dynamics at microtesla fields alter the optimal matching from the traditional SABRE-SHEATH picture. Further development of this approach could lead to new ways to rapidly, cheaply, and simply hyperpolarize a broad range of substrates (e.g. metabolites with carboxyl groups) for various applications, including biomedical NMR and MRI of cellular and in vivo metabolism.

Synthesis, spectroscopic and DFT studies of copper(I) complexes inserting the electron-donating groups into pyridine-imidazole ligands vis an acetylide linker

The three Cu(I) complexes [Cu(POP)(N<^>N)]PF6, N<^>N = 2-(1H-imidazol-2-yl)-5-(p-tolylethynyl)pyridine (P1), 2-(1H-imidazol-2-yl)-5-((4-methoxyphenyl)ethynyl)pyridine (P2), 4-((6-(1H-imidazol-2-yl)pyridin-3-yl)ethynyl)-N,N-diphenylaniline (P3), were prepared and characterized. The different electron-donating groups such as methylphenyl, methoxyphenyl, and diphenylamine substituents were functionalized onto the pyridine ring part of the diimine ligands through an acetylide linker to enhance the light-absorption abilities, giving the larger light-absorption ability and red-shifted absorption bands for the investigated Cu(I) complexes. Yellow emissions in the range of 579-590 nm with quantum yields of 8.40-15.1% can be observed for all complexes at room temperature. The photophysical properties were further explained by DFT and TDDFT methods.

Dual Trapping of a Metastable Planarized Triarylborane pi-System Based on Folding and Lewis Acid-Base Complexation for Seeded Polymerization

We report the kinetically controlled supramolecular polymerization of boron-containing p-conjugated molecules, which was enabled by a seeding method based on dual trapping of a metastable state by synergistic intramolecular hydrogen bonding and Lewis acid-based complexation. Planarized triarylborane-based 1, which bears a diamide chain with chiral alkyl groups, was synthesized. Upon cooling, the solution of monomer 1 afforded a supramolecular polymerization in a cooperative manner to form helical supramolecular nanostructures with intense J-type aggregate emission. In the presence of pyridine, the triarylborane moiety formed a Lewis acid-base complex, which enhances the stabilization of the metastable monomeric state. An assembly incompetent structure with a folded diamide chain conformation and a pyridine moiety axially coordinated to the boron atom is responsible for slowing the spontaneous aggregation. The seeding method was successfully applied to the solution to produce homogeneous nanofibers even at a high (millimolar-level) concentration. This unprecedented kinetic control via dual trapping provides an effective method to achieve seed-initiated polymerization under concentrated conditions.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 88150-62-3, you can contact me at any time and look forward to more communication. SDS of cas: 88150-62-3.

A supramolecular 3D structure constructed from a new metal chelate self-assembled from Sn(NCS)(2) and phenyl(pyridin-2-yl)methylenepicolinohydrazide

Synthesis and detailed structural characterization of a new coordination compound [Sn(HL)(2)(NCS)(2)]0.5MeOH (10.5MeOH), synthesised from a mixture of SnSO4 and KNCS with a bulky organic lig and phenyl(pyridin-2-yl)methylenepicolinohydrazide (HL) in MeOH, is reported. The metal is N6O2 octacoordinated by two tridentate ligands HL through the pyridyl-imine units and the carbonyl oxygen atoms, and its coordination sphere is completed by two N-bound isothiocyanate anions to form the mononuclear heteroleptic complex. The crystal packing of 10.5MeOH is strongly dictated by aromatic pyridine and benzene substituents in the structure of coordinated ligands HL . The pyridine rings are involved in intermolecular pi(Py)pi(Py) stacking interactions, yielding a 2D supramolecular layer. These 2D layers are further interlinked in the orthogonal direction through intermolecular pi(Ph)pi(Ph) stacking interactions, yielding a 3D supramolecular structure. The structure of 10.5MeOH is further stabilized by weak non-covalent interactions of the type C-HS and C-H pi(Py). Latter interactions have been studied us ing density functional theory (DFT) and molecular electrostatic potential (MEP) surface calculations and characterized using the quantum theory of atoms-in-molecules (QTAIM).

A new and efficient pyridine-2,6-dicarboxamide-based fluorescent and colorimetric chemosensor for sensitive and selective recognition of Pb2+ and Cu2+

A new fluorene-bearing pyridine-2,6-dicarboxamide (3) as an effectint fluorescent and colorimetric cation sensor was successfully synthesized and well-characterized using FT-IR, NMR, ESI+-MS and elemental analysis. The metal ion binding ability of the chemosensor 3 in the presence of different metal ions was investigated using UV-vis, fluorescence experiments and results exhibited a desirable selectivity and significant sensitivity of the chemosensor 3 for the detection of Cu2+ and Pb2+ ions. The association constant (K-a) of 3-Cu2+ and 3-Pb2+ complexes were determined to be 8.89 x 10(3) M-1 and 5.65 x 10(8) M-2, respectively. The obtained limit of detection (LOD) values (1.49 x 10(-6) M for Cu2+ and 2.31 x 10(-6) M for Pb2+) clearly revealed the considerable sensitivity of the chemosensor 3.

Spin-Orbit Coupling Accelerates the Photoinduced Interfacial Electron Transfer in a Fullerene-Based Perovskite Heterojunction

In this work, we explore the interfacial properties of the C-60-Py@MAPbI(3) heterojunction of the PbI-terminated MAPbI(3) (001) surface and pyridine-functionalized C-60-Py fullerene derivative through both collinear and noncollinear density functional theory calculations with and without spin-orbit coupling (SOC) effects. C-60-Py is bound to the MAPbI(3) surface through interfacial Pb-O and Pb-N bonds. Although C-60-Py@MAPbI(3) is predicted to be the same type II heterojunction at all of the computational levels considered, the SOC effects largely decrease the energy gap of the first conduction bands of C-60-Py and MAPbI(3), thereby accelerating the interfacial electron transfer. Further dynamics simulations show that the inclusion of the SOC effects induces the transfer of approximately 80% of electrons from MAPbI(3) to C-60-Py within 1 ps. The work demonstrates that the SOC effects are indispensable for the interfacial properties of C-60-Py@MAPbI(3) and could also play a non-negligible role in tuning the optoelectronic properties of fullerene-based or similar perovskite devices.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 88150-62-3. Safety of Phthaloylamlodipine.

Two tridentate pyridinyl-hydrazone zinc(II) complexes as fluorophores for blue emitting layers

Two new complexes were obtained by reaction of zinc (II) acetate with 4-fluoro-N’-(pyridin-2-ylmethylene) benzohydrazide or with 4-(hexyloxy)-N’-(pyridin-2-ylmethylene)benzohydrazide ligands in pyridine. Both ligands have a pyridinyl-hydrazone moiety able to act as a mono-negative tridentate ligand toward zinc ion in 2:1 stoichiometric ratio, producing an octahedral environment. The derived complexes are poor emitters in diluted solution. Instead, they exhibit intense blue fluorescence in the solid state due to AIE (aggregation induced emission) effect. The crystalline complexes are bright yellow in natural light and blue under UV-visible light with remarkable Stokes Shifts. Their photoluminescence quantum yields are ranging 20-30%, making them very promising as fluorophore dopants for blue emissive layers. One ligand and its complex were characterized by single crystal X-ray diffraction analysis that revealed an almost planar conformation of two ligands coordinated to the metal and the presence of significant pi-pi stacking of molecules at about 3.4 angstrom.
