Abstract Graphitic carbon nitride (GCN) nanosheets decorated with iron nanoparticles (Fe/g-C 3 N 4 ) were synthesized and used as catalysts in FTS. The crystal structure and morphology of Fe/g-C 3 N 4 were characterized with XRD, FT-IR, HRTEM, EXAFS, BET, and its texture evolution during Fischer-Tropsch synthesis was monitored. It was shown that there were two types of iron species in Fe/GCN, i.e., “dissolved iron”, in which irons dissolved into g-C 3 N 4 matrix as single atoms, and formed mainl...

Abstract A copper(II)-phenanthroline hybrid material based on the SBA-15 architecture was prepared using a two-step synthesis through co-condensation of 5-[N,N-bis-3-(triethoxysilyl)propyl]ureyl-1,10-phenanthroline with tetraethoxysilane, followed by coordination of Cu(OAc) 2 . The obtained hybrid material, Cu(II)phen@SBA-15 , was fully characterized, at each stage of the preparation, by means of bulk and molecular techniques to assess both textural and structural catalyst features using XRD, XP...

Abstract Bearing the alkylation of alkene substrates using alcohol as solvent, catalysed by the cationic Ru-based catalyst [(C 6 H 6 )(PCy 3 )(CO)RuH] + , DFT calculations have been carried out to get mechanistic insights of such an environmental friendly reaction. Hard experimental conditions of Yi and coworkers [ Science 2011 , 333 , 1613] allow the formation of a C C bond between indene and ethanol. The predicted mechanism suggests a cationic Ru-alkenyl species once two equivalents of indene ...

Abstract In this work, the mixed oxide catalysts Cu 0.1 La 0.1 Ce 0.8 O with the different grinding time (denoted as x, x = 0, 1, 5, 10, 15, or 20) for low-temperature selective catalytic reduction (SCR) of NO with CO are prepared by the grinding method. XRD, SEM, BET, XPS, in situ DRIFTS, H 2 -TPR, and O 2 -TPD measurements are used to characterize the catalysts CLC xh, which is objective to illuminate the influence of the grinding on the physicochemical and catalytic properties of CLC xh compo...

Abstract A detailed kinetic model for formic acid (HCOOH) decomposition on oxide vanadium-titanium (7.3%V 2 O 5 /92.7%TiO 2 ) catalyst has been developed based on transient kinetic studies and IR spectroscopy in situ . Formic acid decomposition to CO 2 (dehydrogenation) and to CO (dehydration) proceeds via different mechanistic routes. Dehydrogenation proceeds via the conventional “formate” mechanism and include reversible dissociative adsorption of formic acid on vanadyl group V = O. The oxygen...

Abstract An Ag(I)-functionalized MOF, MIL-101-SO 3 Ag, was synthesized and demonstrated to be an efficient and environmentally friendly catalyst for the syntheses of propargylamines through A 3 coupling of aldehydes, terminal alkynes and amines. A quite small amount of the catalyst can efficiently catalyze the reactions of aliphatic aldehydes, alkynes, and amines under solvent-free conditions to give propargylamines in excellent yields (>90%). The TOF can be as high as 6600 h −1 . The catalytic ...

Abstract In this study, a novel decontamination method against mustard agent simulant 2-chloroethyl ethyl sulfide (CEES) was conducted with 30% H 2 O 2 aqueous solution in 1-butyl-3-methylimidazolium based ionic liquids (ILs). More than 99% of the CEES was oxidized within H 2 O 2 /[BMIm]HCO 3 at a concentration of 20 mg mL −1 in 30 min with the corresponding sulfoxide yield more than 97%. Decontamination was effective at very low temperatures (−32 °C). [BMIm]HCO 3 can be recycled 4 times without...

Abstract Ruthenium(0) nanoparticles supported on nanohafnia (Ru 0 /HfO 2 ) were prepared by impregnation of ruthenium(III) cations on the surface of hafnia followed by their reduction with sodium borohydride at room temperature. Ru 0 /HfO 2 samples were isolated from the reaction solution by centrifugation and characterized by a combination of advanced analytical techniques including ICP-OES, BET, XRD, SEM-EDS, TEM, XPS. The catalytic activity of Ru 0 /HfO 2 samples with various ruthenium loadin...

Abstract Photocatalytic conversion of CO 2 into hydrocarbon fuels using semiconductor photocatalysts has attracted great attention, which is considered as a promising approach to resolve the energy shortage and greenhouse effect. In this work, ordered mesoporous g-C 3 N 4 (mpg-C 3 N 4 ) nanosheets supported CdIn 2 S 4 nanocomposites were successfully fabricated by a hard-template combinated with hydrothermal method. The hybrids showed highly efficient photocatalytic activities for the reduction ...

Abstract Porous carbon spheres (PCSs) were synthesized by surfactant assisted-hydrothermal method and the oxygen functional groups and structure defects of PCSs were controllably modulated by O 3 treatment technology. Especially, the treated time and temperature played the significant roles in this strategy. Notably, the SEM indicated that the morphology and particle size of PCSs had not been changed basically after O 3 treatment. However, the specific surface area of PCSs decreased with increas...
