The structural parameters and average molecular structures of the asphaltenes obtained from Aguacate oilfield, located in Golden Lane Mexico, have been investigated combining experimental analysis simulation. polycyclic aromatic hydrocarbon (PAH) region, number fused rings (nFAR), isomers polydispersity PAH core, architecture, weight, substituents core determined by means 13C single-pulse excitation (SPE) nuclear magnetic resonance (NMR) combination with distortionless enhancement...
The formation of cerium hydroxide was studied, and its capacity as a corrosion inhibitor on aluminum substrates evaluated. These particles were deposited by immersing the substrate in bath with nitrate hydrogen peroxide. Four different immersion times used to determine differences behavior from low concentrations an excess surface. coatings analyzed morphologically scanning electron microscope (SEM) optical microscope, chemically energy dispersive spectroscopy (EDS) X-ray photoelectron...
Nowadays, 13C nuclear magnetic resonance (NMR) is used in the structural study of asphaltenes. However, different carbon types polycyclic aromatic hydrocarbon (PAH) core asphaltenes, to be able establish their main backbone, have been reported NMR chemical shift ranges by authors literature. Therefore, present study, for types—(a) Y-carbons (CY) or internal triple bridgehead carbons; (b) external peripheral atoms at junction two fused rings, double carbons (CAP3); (c) bonded hydrogen (CAH);...
We investigated the influence of structural and textural properties along with chemical environment Zn 3 [Co(CN) 6 ] 2 , Cd Fe modified phases on catalytic performance in cycloaddition reaction between styrene oxide CO .
AuRh nanoparticles supported on TiO2 P25 were synthesized by two sequential deposition methods: deposition-precipitation with urea (DPU) and impregnation (IMP)-DPU. Segregated (RhcoreAushell ball-cup-type, Janus-type arrangements) observed in gold-rhodium bimetallic catalysts, but mainly ball-cup-type found catalysts prepared IMP-DPU. XPS analysis of before after reaction allowed concluding that interaction metallic state was an important factor to avoid the oxidation rhodium during CO...
Small rhodium nanoparticles (ca. 3.5 nm) were prepared by the decomposition of an organometallic precursor under hydrogen pressure in glycerol using 1‐thioglycerol as stabilizer. Full characterization solid state [HR‐TEM, EDX, XPS] showed a fcc structure for Rh 0 /Rh I capped with thiolate ligand. Reduction different functionalities, including nitro groups and imines, was applied to tandem reductive amination aldehydes primary secondary amines, synthesis N ‐substituted anilines from...
The electrochemical capacitance for a double layer of ordered mesoporous carbon (OMC) nanofibers functionalized under differing conditions is presented. OMC were prepared using the molding method from SBA-15 and sucrose. Functionalisation was performed varying HNO3 concentrations at 110°C 120°C assisted by microwave radiation over 3 minutes. transmission electron micrographs resulting fibers are reported. capacitance, surface area functional groups as functions acidity heat treatment...
In microporous materials, the guest species interacts with host framework and can modify electronic structure of that last one related physical functional properties. For instance, this possibility is relevant regarding their potential applications in sensor actuator device construction. contribution, we are reporting effect tiny aromatic molecules (benzene, toluene, furan, thiophene) adsorption Fe(pyrazine)[Fe(CN)5NO]. This material has a porous appropriate for small molecules, at same...
RhNPs supported on mesoporous silica functionalized with nicotinamide groups provided active hydrogenation catalysts for several functional groups, wherein the shape and size of are maintained after catalysis.
