“…These acidic and basic sites along with redox properties suggest the possibility to design unique bifunctional catalysts. In recent years, many reports have been published on the catalytic application of amorphous AlP and MAlPs in a wide range of organic transformations including dehydrogenation [5], cracking [6], transesterification [7], and alkylation [8], and as supports for other catalytic systems such as oxides [9].…”

“…The hysteresis is closest in shape to the H3 type, corresponding to aggregates of platelike particles giving rise to slit-shaped pores. While the absence of a knee implies negligible micropore volume, the steep rise in the adsorbed volume of nitrogen at a relative pressure > 0.7 implies the broad pore size distribution . The volume adsorbed was much higher after supporting with MWNTs, indicating a higher total surface area.…”

Layered double hydroxides (LDH)-derived mixed metal oxides (MMO) are considered as promising solid sorbents for CO2 capture in the temperature range of 350–500 °C. Accordingly, they find potential applications in the sorption enhanced water–gas shift process and in removal of CO2 from hot flue gas/syngas. Numerous strategies have been explored to improve the CO2 capture property of LDH-derived MMO under the conditions of intended applications. These strategies include novel sorbents by replacement of cations and intercalation of organic anions on Mg–Al LDH, development of LDH-based hybrid/composite materials, optimization of synthesis conditions to control particle size, and method development for different types of alkali impregnation. The present work involves synthesis of a Mg–Al LDH/multiwalled carbon nanotubes (MWNTs) composite and explores its applicability for CO2 capture under dry conditions. Additionally, K2CO3 is impregnated onto the composite to study the effect of alkali promotion. The K2CO3-promoted Mg–Al LDH/MWNT composite exhibited a fresh adsorption capacity of 1.12 mmol g–1 at 300 °C under a total pressure of 1 bar. The enhanced CO2 sorption capacity of composites in comparison with their pristine counterparts can be attributed to improved particle dispersion. Further, the K2CO3-promoted Mg–Al LDH/MWNT composite shows an average working capacity of 0.81 mmol g–1 over 10 cycles in the temperature range of 300–400 °C. The deactivation model provides excellent predictions of the experimental CO2 breakthrough curves obtained with various sorbents. The values of model parameters are comparable with those reported in the literature.
