The aim of this work was to obtain an in-depth understanding the U(VI) adsorption mechanism over amino-functionalized mesoporous silica SBA-15 and highlights its high efficiency in aqueous media for removal preconcentration. samples were synthesized functionalized by both grafting co-condensation methods, using different alkyl-substituted amine groups characterized X-ray diffraction, N2 physisorption, Fourier transform infrared spectroscopy, elemental C-H-N-S analyses. properties evaluated...
Abstract The development of reliable electrolyzers is closely related to the a cost‐effective highly active and stable electrocatalysts for oxygen evolution reaction (OER). Herein, simple method used synthesize non‐noble metal‐based electrocatalyst OER by synergistically coupling catalytically cobalt layered double hydroxide (Co‐LDH) with electrically conducting 2D transition metal carbide, Ti 3 C 2 T x MXene. synergy between these two bidimensional materials (Co‐LDH ), evidenced electron...
Adequate foetal growth is primarily determined by nutrient availability, which dependent on placental transport and metabolism. We have used (1)H nuclear magnetic resonance (NMR) spectroscopy to probe the metabolic adaptations associated with premature birth.The profile in NMR spectra of plasma taken immediately after birth from umbilical vein, artery maternal blood were recorded for mothers delivering very-low-birth-weight (VLBW) or normo-ponderal full-term (FT) neonates.Clear distinctions...
Abstract Electric field‐induced decomposition of ammonia into hydrogen and nitrogen was investigated over CeO 2 , Fe‐, Ru‐ deposited CePO 4 Sr‐doped CeZrO in a packed bed down‐flow reactor. The effect applied current, concentration feed, residence time examined using alone. conversion also studied with respect to reduction temperature, loading type the metal. activity results have been analyzed terms surface, morphological electrical characterization catalysts. Among metal‐deposited...
Oxidative dehydrogenation of hydrocarbons (ODH) converts propane and/or ethane into propylene ethylene, which are important compounds in the chemical industry. Unlike steam cracking, ODH offers a high theoretical conversion to olefins and lower energy consumption. The reaction was studied using VOX/Al2O3 catalysts prepared by wet impregnation. conditions were widely varied, with temperatures ranging from 300 550 °C, C3/O2 ratio 1.6 3.3, vanadium content 1 11 wt %. It observed that these...
Abstract A polyol-assisted solvothermal route is used to synthesize Ni x Fe y nanoalloys supported on a highly electron conductive 2D transition metal Mo 2 CT MXene. Structural, morphological and chemical characteristics of the materials are determined using several physicochemical techniques. The MXene support allows not only formation nanostructured metallic nanoalloys, but also favors interfacial charge transfer for oxygen evolution reaction (OER). @Mo material with Ni/Fe ratio 2.66 leads...
A bimetallic cobalt molybdenum sulfide (Co 0.5 Mo S x ) material was studied as candidate electrocatalyst to replace platinum-based cathode for HER reaction in alkaline media. The Co obtained from a hydrothermal synthesis methodology employing sodium diethyldithiocarbamate sulfurizing agent, non-conventional compound. recovered physicochemically characterized by XRD, Raman spectroscopy, TEM and XPS measurements. Analogous monometallic sulfides were also synthesized compare their activities...

Cobalt molybdenum sulfide (Co0.5Mo0.5Sx) was evaluated, as an alternative cathode catalyst for hydrogen large scale production in anion exchange membrane water electrolyzer (AEMWE). Performance testing a Co0.5Mo0.5Sx//Ir single cell fed with 0.1 mol L–1 KOH exhibited the best activity reported to date transition metal cathodes alkaline media. The aforementioned presented good stability during 40 h of operation at 2 V; addition, it has most its current density degradation recovered beginning...
Mesoporous Co3O4 mixed CoO onto reduced graphene oxide (rGO) nanocomposites were obtained by an easy surfactant-free synthesis using urea as hydrolyzing agent. This route enabled nanomaterials presenting tuned morphology, surface composition and oxide-rGO interactions revealed the different characterization techniques. Indeed, nanostructures varied from broom-like, chrysanthemum-like to micro-sized sheet-like morphologies. The amount of phase was shown be gradually rising increases being...
MXenes are two-dimensional transition-metal carbides and nitrides with an attractive combination of physicochemical properties, gaining notable potential in many applications. Currently, MXene synthesis is mainly performed from powder precursors whose purity grain size define the quality flake 2D sheets, typically not exceeding 2–3 μm. In this work, we successfully synthesize macroscopic nanolayered V2CTz lateral dimensions larger than 25 μm a V2AlC single crystal by exploiting new strategy...
2D MXenes have gained an ever-increasing attention in various application fields owing to the combination of their layered structure with excellent physico–chemical properties. MXene properties can be strongly tuned by modifying M element Mn+1XnTx structure. Among them, Mo-based are beginning successfully explored many areas.
