We report here, and rationalize, a synergistic effect between non-noble metal oxide catalyst (CuO) high-frequency ultrasound (HFUS) on glucose oxidation. While CuO HFUS are able to independently oxidize gluconic acid, the combination of with led dramatic change reaction selectivity, glucuronic acid being formed as major product. By means density functional theory (DFT) calculations, we show that, under ultrasonic irradiation water at 550 kHz, surface lattice oxygen traps H· radicals stemming...
A novel Pd-based catalyst hosted over a nitrogen enriched fibrous porous-organic-polymer with high density of step sites and exhibits versatile catalytic performance different types vegetable oils to furnish long chain diesel-range alkanes.
Porous organic polymers (POPs) constructed through covalent bonds have raised tremendous research interest because of their suitability to develop robust catalysts and successful production with improved efficiency. In this work, we designed explored the properties catalytic activity a template-free-constructed, hydroxy (-OH) group-enriched porous polymer (Ph-POP) bearing functional Pd nanoparticles (Pd-NPs) by one-pot condensation phloroglucinol (1,3,5-trihydroxybenzene) terephthalaldehyde...
Antioxidant efficiency of all-trans-retinol has been studied on the basis characteristic thermochemical properties using density functional theory. The influence solvent polarity also evaluated. It is found that retinol may act in parallel as an effective antioxidant via H atom donating well a pro-oxidant yielding reactive hydroxyl radical. In fact, lowest values bond dissociation enthalpy were at C18–H and C18–OH positions. Retinol was determined to be good electron donor but bad acceptor...
In this study, graphene nanosheet-supported ultrafine Cu nanoparticles (NPs) encapsulated with thin mesoporous silica (Cu-GO@m-SiO2) materials are fabricated particle sizes ranging from 60 to 7.8 nm and systematically investigated for the oxidative coupling of amines produce biologically pharmaceutically important imine derivatives. Catalytic activity remarkably increased 76.5% conversion benzyl amine NPs 99.3% exclusive selectivity N-benzylidene-1-phenylmethanamine NPs. The superior...
Post-combustion CO2 capture, storage, and separation have garnered colossal research interest in the energy industry, although realistic implementation of available porous adsorbents is restricted owing to their cost competitiveness, stability, scalability issues. The integration heteroatom functionalities (N, O, or S) at molecular level into organic skeleton framework materials endowed them with superior mitigate greenhouse gases. In this work, we successfully introduced triazine–thiophene...
A new copper(ii) complex, [Cu(LC)(Ibu-phen)(H2O)2](ClO4)2 (LC: lidocaine, Ibu-phen: ibuprofen amide-phenanthroline), was synthesized and characterized. The antioxidant activities of the free ligands complex were evaluated by in vitro experiments theoretical calculations using density functional theory (DFT). Structures ligand Ibu-phen identified 1H 13C NMR, FT-IR spectroscopies, mass spectrometry, thermogravimetric analysis elemental analysis. potentials LC as well also DPPH˙, ABTS˙+, HO˙...
Surface enhanced Raman scattering (SERS) experiments and quantum chemical calculations (using density functional theory) on the interactions of chlorpyrifos (CPF), which is an intensively used pesticide, with a roughed silver nanoparticle surface were thoroughly investigated to study inherent molecular mechanism. Ligand–cluster interaction geometries show that CPF molecule mainly adsorbed via both S atom pyridine ring involving covalent Ag···S coordination as well van der Waals...
Anthropogenic carbon dioxide (CO2) emission is soaring day by due to fossil fuel combustion fulfill the daily energy requirements of our society. The CO2 concentration should be stabilized evade deadly consequences it, as climate change one major greenhouse gas emission. Chemical fixation other value-added chemicals requires high its stability at highest oxidation state, creating a tremendous challenge scientific community fix and prevent global warming caused it. In this work, we have...
The electrochemical fixation of carbon dioxide (CO2) into organic halides is one the most prominent strategies for mitigating atmospheric CO2 emission, along with difficulties associated toxic and carcinogenic halogenated compounds. Cu-based nanomaterials have been explored numerous applications in nanotechnology, including electrocatalysis, catalytic transformations, photocatalysis. In this work, we designed developed a Cu-embedded carbazole-derived porous polymer (Cu@Cz-POP) nanohybrid by...
An experimental and kinetic study of the influence additives on selective noncatalytic reduction (SNCR) process is presented. Experiments were performed a lab-scale reactor suitable to investigate important operating parameters (flue gas temperature, residence time, amount reducing agent, initial NOx concentration, etc.) SNCR efficiency. Several chemical compounds such as CH4, C2H6, C2H4, C2H2, CH3OH, C2H5OH, CO, which are usually used in literature for process, have been evaluated. The...
