Zhao, Ziming published the artcilePreparation of a magnetic mesoporous Fe3O4-Pd@TiO2 photocatalyst for the efficient selective reduction of aromatic cyanides, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is iron oxide palladium titania mesoporous composite photoreduction photocatalyst hydrogenation.

Herein, a hierarchical magnetic mesoporous microsphere was successfully prepared as a photocatalyst via a simple and reproducible route. Typically, Pd nanoparticles (NPs) were evenly dispersed on the surface of a magnetic Fe3O4 microsphere and then coated with a porous anatase-TiO2 shell to form Fe3O4-Pd@TiO2. The core-shell structure could efficiently suppress the conglomeration of Pd NPs during the calcination process at high temperatures as well as the shedding of Pd during the catalytic reaction process in the liquid phase. The as-prepared photocatalyst was characterized by TEM, XRD, XPS, VSM, and N2 adsorption-desorption. Fe3O4-Pd@TiO2 exhibits high photocatalytic activity for the selective reduction of aromatic cyanides to aromatic primary amines in an acidic aqueous solution Moreover, this magnetic photocatalyst could be easily recovered from the reaction mixture by an external magnet and reused five times without significant reduction in its activity. The superior photocatalytic efficiency of the proposed photocatalyst may be attributed to its high charge separation efficiency and charge transfer rate, which are caused by the Schottky junction and large interface area. The results indicate that the strategy of coating the active noble metal sites with a mesoporous semiconductor shell has a significant potential for application in metal-semiconductor-based photocatalytic reactions.

Ming, Zheng published the artcileDye-polyoxometalate coordination polymer as a photo-driven electron pump for photocatalytic radical coupling reactions, Related Products of nitriles-buliding-blocks, the main research area is coordination polymer preparation electron pump photocatalytic radical coupling.

To alleviate diffusion-limited photoinduced electron transfer (PET) in solution, a triphenylamine-derived dye and a Keggin polyoxometalate-type electron relay were coupled into a coordination polymer to photoinduce long-lived charge-separation pairs with enough reductive/oxidative potential to pump multiple electrons unidirectionally from external electron donors to acceptors, thus furnishing photocatalytic radical couplings to afford value-added α-amino C-H arylation products.

Babu, Venkata Nagarjuna published the artcileExocyclic N-Acyliminium Ion (NAI) Cyclization: Access to Fully Substituted Oxazoles and Furocoumarins, Application of Picolinonitrile, the main research area is one pot synthesis oxazole furocoumarin UV vis fluorescence study; exocyclic acyliminium ion intermediate cyclization.

A concise, one-pot route to oxazoles and furocoumarins has been reported. The key step in this transformation involves in situ generation of N-acyliminium ion (NAI) precursor under catalyst and solvent-free conditions and their further transformations promoted by superacid in the same pot. We have also presented the exptl. evidence for the involvement of proto-solvated novel exocyclic N-acyliminium ion. Further, the UV-visible and fluorescence studies revealed that few of the compounds reported here exhibited emission of blue light upon irradiation in EtOH in the region of 404-422 nm.

Ocansey, Edward published the artcileIridium and Palladium CO2 Hydrogenation in Water by Catalyst Precursors with Electron-Rich Tetrazole Ligands, Quality Control of 100-70-9, the main research area is tetrazolylpyridyl iridium palladium complex preparation catalyst carbon dioxide hydrogenation; iridium chloride cyclometalation reaction tetrazolylpyridine ligand; palladium chloride cyclometalation reaction tetrazolylpyridine ligand.

Hydrogenation of CO2 to formate serves as a means of H2 storage. By using robust, electron-rich and bulky NN bidentate tetrazolylpyridyl ligands, the authors prepared CO2 hydrogenation Ir(III) and Pd(II) catalyst precursors (3-7) that operate in H2O as a solvent. In situ1H NMR spectroscopic data obtained when the hydrogenation catalyst is 5, detects a hydrido bridged binuclear Ir intermediate compound is formed prior to the formation of the catalytically active Ir hydride species. This hydrido bridged Ir intermediate is observable by in situ1H NMR spectroscopy even after extended periods of storage. Product formation in the CO2 hydrogenation, catalyzed by these tetrazolylpyridyl Ir and Pd catalysts, proceeds via either CO2 hydrogenation or NaHCO3 reduction

Wang, Wenbo published the artcileTricycloquinazoline-containing 3D conjugated microporous polymers and 2D covalent quinazoline networks: microstructure and conductivity, Synthetic Route of 1885-29-6, the main research area is tricycloquinazoline conjugated microporous polymer covalent quinazoline network microstructure conductivity; gas adsorption hydrogen evolution reaction electrocatalyst.

Conjugated microporous polymers (CMPs) and covalent triazine frameworks (CTFs) with conjugated linkages and nanochannels have been showcased as a new platform in extensive fields. Here, by tuning the geometry of the N-rich skeleton tricycloquinazoline (TQ) unit, isomers of the 3D amorphous conjugated microporous polymer (TQ-CMP) and 2D laminar covalent quinazoline network (TQ-CQN) are synthesized. The derived diverse microstructure and elec. conductivity related to the applications of gas adsorption and the hydrogen evolution reaction (HER) are systematically discussed. TQ-CMP fabricated with an internal crosslinking network reveals a notable uptake of 25.6 wt% CO2 and of 2.91 wt% CH4 at 273 K and 1 bar, higher than most reported POP materials, which could be attributed to the higher BET surface area (781.0 m2 g-1) and dispersed pore size (1.1 nm to 13.1 nm) for guest mol. absorption. In contrast, both the modulated electronic structure of the precise π-conjugate planes and the vertically ordered one-dimensional channels endow TQ-CQN with more built-in catalytic sites and rapid electron transmission for the HER. Without any noble metal doping, the excellent catalytic activity and faster reaction kinetics of TQ-CQN are epitomized by the achieved lower overpotential of 80 mV and the Tafel slope of 40 mV dec-1.

Panomsuwan, Gasidit published the artcileIn situ solution plasma synthesis of silver nanoparticles supported on nitrogen-doped carbons with enhanced oxygen reduction activity, Category: nitriles-buliding-blocks, the main research area is silver nanoparticle nitrogen doped carbon electrocatalyst plasma synthesis; oxygen reduction reaction silver nanoparticle nitrogen doped carbon electrocatalyst.

Silver nanoparticles supported on nitrogen-doped carbons (Ag/NC) were in situ synthesized by a solution plasma process. In the solution plasma, Ag nanoparticles were produced via the sputtering of Ag electrode, while the NC supports were simultaneously synthesized from 2-cyanopyridine (C6H4N2). The results of the characterization show that Ag nanoparticles had good crystallinity and the NC supports possessed an amorphous structure. The oxygen reduction reaction (ORR) catalyzed on Ag/NC proceeded via the co-existence of two and four-electron pathways in alk. solution, with the four-electron pathway being found to be more dominant. An enhanced ORR activity of Ag/NC was attributed to the synergistic effect of Ag nanoparticles and NC supports. Moreover, Ag/NC exhibited long-term durability and high resistance to methanol oxidation in comparison with the com. Pt/C catalyst.

Hui, Heping published the artcileStructure characterization, antioxidant and hypoglycemic activity of an arabinogalactoglucan from Scutellaria baicalensis Georgi, Quality Control of 91-15-6, the main research area is Scutellaria arabinogalactoglucan SBP1 antioxidant hypoglycemic agent; Antioxidant and hypoglycemic activity; Arabinogalactoglucan; Scutellaria baicalensis Georgi; Structure characterization.

An arabinogalactoglucan SBP-1 was purified from Scutellaria baicalensis by DEAE-52 and Sephadex G-100 column chromatog. The structure of SBP-1 was characterized using HPLC, IR, GC-MS, 1-D and 2-D NMR. The antioxidant and hypoglycemic activity of SBP-1 was investigated by vitro evaluation. The results showed that SBP-1 was composed of arabinose, glucose and galactose in a molar ratio of 1.0:5.9:1.1 and its Mw were 91,156. The backbone of SBP-1 was mainly composed of repeating →1-α-D-Glcp-(4 → 1)-α-D-Glcp-(3 → 1)-α-D-Galp-(4→. The braches were composed of →2)-α-L-Araf-(1→, →3)-β-D-Glcp-1→ and α-D-Glcp-1→, which mainly substituted at O-6 of Glc, while terminal residue was α-L-Araf-1→ and α-D-Glcp-1→. Vitro bioactivity showed that SBP-1 had dose-dependent antioxidant and hypoglycemic activity. The scavenging rate on ABTS, DPPH, hydroxyl and superoxide radicals was all beyond 60% as SBP-1 concentration reached 4 mg/mL, and the inhibition rate on α-glucosidase and α-amylase was both more than 80%, which was closely to that of acarbose.
