The lithium silicates have attracted scientific interest due to their potential use as high-temperature sorbents for CO2 capture. electronic properties and thermodynamic stabilities of with different Li2O/SiO2 ratios (Li2O, Li8SiO6, Li4SiO4, Li6Si2O7, Li2SiO3, Li2Si2O5, Li2Si3O7, α-SiO2) been investigated by combining first-principles density functional theory lattice phonon dynamics. All these examined are insulators band-gaps larger than 4.5 eV. By decreasing the ratio, first valence...
Lithium oxosilicate (Li8SiO6) was successfully synthesized via a solid-state reaction. The sample's structure and microstructure were characterized using X-ray diffraction, scanning electron microscopy N2 adsorption. CO2 chemisorption capacity evaluated dynamically isothermally. Li8SiO6 found to chemisorb over wide temperature range with maximum weight increase of 52.1 wt%, which corresponds 11.8 mmol per gram ceramic. Using different thermogravimetric analyses some structural...
Abstract In this work, a detailed investigation of the rheological and mechanical properties nanocomposites based on polyethylene terephthalate (PET) montmorillonite clays is presented. A series additives [maleic anhydride (MAH), pentaerythritol (PENTA), alkylammonium chlorides from amines various chain lengths] were used as compatibilizers. The influence behavior PET matrix was evaluated separately, through their individual contributions. To shed more light reported decrease in melt...
Different Al-containing Li4SiO4 samples (Li4+x(Si1–xAlx)O4 solid solutions) were obtained by mechanosynthesis and then characterized structurally (X-ray diffraction (XRD) solid-state NMR) microstructurally (N2 adsorption scanning electron microscopy (SEM)). While NMR results showed that the aluminum (silicon) presented some distortion after milling process, process tended to increase Li4+x(Si1–xAlx)O4 surface areas. The tested dynamically isothermally in CO2 chemisorption at high...
El olote de maíz se considera un residuo agrícola producido por la separación del grano y mazorca, el cual material con una elevada masa lignocelulósica. Anualmente, produce en grandes cantidades debido a actividad agroindustrial México, pesar ello, éste no representa ningún valor monetario para los productores, lo que termina siendo incinerado, provocando inestabilidad cambio climático. No obstante, extracción nanoscelulosa resulta atractiva científicos sector empresarial, pues tiene...
Abstract In this study, we investigated the performance of graphene oxide (GO)-based catalysts, including commercially available GO, GO synthesized via All Kemie Sus method, and GO/TiO 2 composites, for CO reduction under both UV visible light irradiation. The catalysts were systematically characterized using XRD, SEM, FTIR, EDS, UV, XPS techniques to elucidate their structural chemical properties. Our findings reveal remarkable versatility these materials, demonstrating ability produce a...
The pursuit of effective climate change mitigation strategies is driving research into geological carbon dioxide (CO2) storage. present work explores the interaction CO2 with carbonate rocks from El Abra formation in Tampico-Misantla basin, focusing on comparative influence organic matter (OM) content mineralization processes, hypothesizing that variations OM significantly modulate process affecting both rate and type formation. Expanding a previous study, studied injected under...
Sodium metatitanate (Na2TiO3) was successfully synthesized via a solid-state reaction. The Na2TiO3 structure and microstructure were characterized using X-ray diffraction, scanning transmission electron microscopy, N2 adsorption. Then, the CO2 chemisorption mechanism on systematically analyzed to determine influence of temperature. capacity evaluated both dynamically isothermally, products reanalyzed elucidate Na2TiO3–CO2 reaction mechanism. Different chemical species (Na2CO3, Na2O,...
Different sodium zirconate solid solutions containing aluminum (Na2(Zr1–xAlx)O3) were synthesized via a solid-state reaction. Samples characterized using X-ray diffraction and nuclear magnetic resonance. Then, samples tested as CO2 captors. Characterization results show that ions can occupy zirconium or sites in the Na2ZrO3 structure. Thus, dissolution is compensated by different structural defects. The capture evaluation shows presence into structure improves chemisorption within certain...
CO2 adsorption at elevated pressure was studied in a Mg–Al (Mg/Al = 3) layered double hydroxide (LDH). The double-layered structure prepared via coprecipitation method. sample's and microstructure evolutions were characterized using X-ray diffraction, scanning electron microscopy, N2 adsorption, thermogravimetric calorimetric analyses. experiments performed between 5 4350 kPa different temperatures (30–350 °C). Elevated showed that this material able to adsorb quantities of depending on the...
