Efficient hybrid-type CO2 adsorbents are synthesized via an electrostatically-derived self-assembly of cationic Mg-Al-LDH 2D nanosheets and anionic polyoxometalate (POM, V10O286- and W7O246-) 0D nanoclusters. The electrostatically-derived self-assembly between exfoliated Mg-Al-LDH 2D nanosheets and POM 0D nanoclusters (W7O246- and V10O286-) yields a high flexibility in the control of the chemical composition and layer-by-layer-ordered intercalation structure with porous structures composed of mesopores and micropores. The hybridization with POM leads to the remarkable enhancement of the CO2 adsorption functionality of Mg-Al-LDH by almost 10 times. Of prime importance is that the CO2 adsorption functionality of the nanohybrid is strongly dependent on the type of guest POM species. This finding strongly suggests that the CO2 adsorption functionality of the LDH-based nanohybrid materials can be optimized via the selection of guest species. The present result clearly demonstrates that the exfoliation-reassembling method is quite effective in synthesizing new LDH nanosheet-based hybrid materials with improved CO2 adsorption functionality.
