Carbon dioxide (CO<sub>2</sub>) capture using solid sorbents has been recognized as a very promising technology that attracted intense attention from both academic and industrial fields in the last decade.
High-density polyethylene (HDPE) polymer nanocomposites containing Zn2Al-X (X= CO3(2-), NO3(-), Cl(-), SO4(2-)) layered double hydroxide (LDH) nanoparticles with different loadings from 10 to 40 wt % were synthesized using a modified solvent mixing method. Synthesized LDH nanofillers and the corresponding carefully characterized X-ray diffraction, scanning electron microscopy, transmission etc. The thermal stability flame retardancy behavior investigated thermo gravimetric analyzer...
The promoting effect of alkali nitrates molten salt on the CO2 capture capacity a commercial MgO was investigated in detail. In particular, ratio Li/Na/K and loading mixture particles were optimized, influence calcination adsorption temperatures evaluated. sample doped with 10 mol % (Li0.3Na0.6K0.1)NO3 demonstrated to possess highest uptake (up 16.8 mmol g–1), which is value reported for based adsorbents literature. adsorption/desorption cycling stability studied using both temperature swing...
The development of technologies that allow us to reduce CO2 emissions is mandatory in today's society. In this regard, we present herein a comparative study adsorption over three types materials: zeolites, layered double hydroxides (LDH), and zeolites coated LDH composites. influence the zeolite Si/Al ratio on sorption capacity along with presence mesopores was investigated. By comparing these results well-known performance LDHs, aim provide insights factors may capture thus providing useful...
Although there are many reports on layered double hydroxide (LDH) derived CO2 adsorbents, none of them have studied the special case LiAl2 LDHs. Here we report first detailed investigation performance LDHs as novel adsorbents. were synthesized using both traditional coprecipitation and gibbsite intercalation methods. All materials thoroughly characterized XRD, SEM, TEM, FTIR, BET, TGA. The capture these investigated a function charge compensating anions, Li/Al ratio in preparation solution,...
Abstract CO 2 reduction is crucial if the effects of this gas on global warming are to be alleviated. We report for first time an alkali carbonate molten salt promoted CaO‐based sorbent with capture performance superior that neat CaO. The influences chemical composition, loading, and melting temperature (Li–Na–K) 3 salts calcination adsorption temperatures were evaluated systematically. microstructural morphological evolution samples during was studied by X‐ray diffraction, scanning electron...
We report a novel hybrid material Na2Mo4O13/α-MoO3 as highly efficient catalytic wet air oxidation (CWAO) catalyst, which showed the highest ever activity at room temperature and atmosphere pressure for degradation of cationic red GTL. SEM TEM analyses indicated that this catalyst has bamboo-shaped nanofiber morphology. In view practical applications, influence some key parameters including operation temperature, calcination volume dye wastewater have been optimized. The mechanism superior...
We demonstrated that analyzing the formed gels containing exfoliated nitrate or glycine intercalated layered double hydroxide (LDH) nanosheets in formamide using X-ray diffraction is a simple and reliable method for determining delamination degree of LDHs formamide, which shows many advantages compared to common characterization technologies.

Electrochemical impedance spectroscopy analyses were utilised to explore the oxygen ion conductivity of alkali metal salts promoted CaO.
Abstract For CaO‐based high‐temperature CO 2 sorbents, excellent cyclic stability is highly desired for its practical applications. Among all techniques, preparation of composites one the most widely accepted strategies, and mixing status between CaO inert supporting material crucial anti‐sintering property. This work provides a new strategy preparing nanometrically dispersed MgO/CaO with significantly improved stability. The so called solvent/nonsolvent synthesis method can endow...
In this paper, the influence of charge compensating anions Layered double hydroxides (LDHs) in LDH-NS/GO nanohybrid for carbon dioxide capture was systematically investigated. The four kinds different anion intercalated LDH were exfoliated and Graphene oxide (GO) nanohybrids synthesized by "exfoliation-self-assembly" method. contribution, CO2 capacity improved introducing GO. And calcination adsorption conditions tested, which proved that can be used a wide temperature range capture,...
LDH/MgCO<sub>3</sub>hybrid multilayer on an Al substrate as a novel high-temperature CO<sub>2</sub>adsorbent is reported.
Abstract Novel layered double hydroxides (LDHs) were prepared by a co‐precipitation method and characterised using X‐ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT‐IR), Thermogravimetric analysis (TGA) scanning electron microscopy (SEM). As‐prepared LDH derived catalysts first evaluated in the gas‐phase conversion of methanol. The results indicate that materials act as selective towards dimethyl ether (DME), methane or light olefins formation, depending on their...
