Catalysts based on combinations between copper and cerium oxides are analyzed with respect to their catalytic properties for preferential oxidation of CO in a H2-rich stream (CO-PROX) by means DRIFTS, XANES, Raman under Operando conditions. The results allow analyzing entities/species responsible the H2 reactions taking place during CO-PROX process. While takes at oxide support interfacial sites its activity correlates degree reduction achieved dispersed particles, apparently proceeds when...
Abstract The purpose of this study was the preparation, characterization and application high-performance activated carbons (ACs) derived from oily sludge through chemical activation by KOH. produced ACs were characterized using iodine number, N 2 adsorption-desorption, Fourier-transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM). carbon prepared under optimum conditions showed a predominantly microporous structure with BET surface area 2263 m g −1 , total pore volume...
This study reviews the most relevant results on synthesis, characterization, and applications of activated carbons obtained by novel chemical activation with FeCl3. The text includes a description mechanism, which compromises three different stages: (1) intense de-polymerization carbon precursor (up to 300 °C), (2) devolatilization formation inner porosity (between 700 (3) dehydrogenation fixed structure (>700 °C). Among synthesis conditions, temperature, and, lesser extent, impregnation...
NH2-MIL-125(Ti) MOFs have been prepared by microwave-assisted synthesis under different conditions of temperature (140–200 ºC) and holding time (15 min to 4 h). The resulting materials tested as photocatalysts for the breakdown six pharmaceuticals in aqueous solution solar simulated irradiation. A full characterization solid samples X Ray Diffraction, N2 adsorption-desorption, UV–visible DRS, photoluminescence techniques was carried out. MOF at 200 ºC 15 microwave radiation displayed...
Lignin has been employed as a precursor to synthesize activated carbons with the aim of lignin-biomass revalorization. The properties these were compared, and best adsorbent was remove two emerging pollutants from water, acetaminophen acetamiprid. adsorption mechanisms pharmaceutical pesticide compounds analyzed, modeled interpreted via statistical physics models. In particular, kinetics isotherms acetamiprid at temperatures between 20 60 °C quantified experimentally. Equilibrium data fitted...
The photocatalytic degradation of methylparaben was investigated under simulated solar light using a synthesised metal–organic framework (UiO-66-NH2). For that purpose, the pollutant spiked in different water matrices: distilled water, from Lima River (Northwestern Portugal), and urban wastewater. Complete removal achieved 1 h reaction. In natural matrices, performance decreased to 70% after 3 reaction, owing physical–chemical properties samples. UiO-66-NH2 photocatalyst revealed high...
Four metakaolins were prepared by calcination of a natural Spanish kaolin (Navalacruz deposit, Zamora province) at 600, 700, 800, and 900 °C. These four metakaolins, more reactive than the parent kaolin, submitted to acid alkaline activations. Acid activation was carried out with 6 M HCl room temperature 90 °C under reflux conditions, times treatment 24 h. Treatment did not produce any alteration in structure or properties metakaolins. conditions for h led removal most octahedral Al3+...
This study reports the photocatalytic degradation of diclofenac by hybrid materials prepared combination graphitic carbon nitride (g-C3N4) and titanium-metal organic framework (NH2-MIL-125), in different mass proportions (MOF:C3N4 25:75, 50:50 75:25). The were fully characterized, their properties compared to those individual components, whose presence was confirmed XRD. porous structure result highly microporous character MOF non-porous one g-C3N4. band gap values very close that component....
This work reports the solvothermal synthesis of UiO-66-based MOFs with three different ligands and its application to breakdown aqueous acetaminophen under simulated sunlight. pharmaceutical is a representative contaminant emerging concern that enters water bodies mainly through wastewater treatment plant discharges. The approach was fitted using zirconium alkoxide as metal cluster precursor 2-aminoterephthalic 2,5-dihydroxyterephthalic acids prepare UiO-66-NH2 UiO-66-(OH)2 MOFs,...
