The Influence of the Charge Compensating Anions of Layered Double Hydroxides (LDHs) in LDH-NS/Graphene Oxide Nanohybrid for CO₂ Capture.

In this paper, the influence of charge compensating anions of Layered double hydroxides (LDHs) in the LDH-NS/GO nanohybrid for carbon dioxide capture was systematically investigated. The four kinds of different charge compensating anion intercalated LDH were exfoliated and the LDH and Graphene oxide (GO) nanohybrids were synthesized by "exfoliation-self-assembly" method. In this contribution, the CO2 capture capacity of LDH was improved by introducing of GO. And the calcination and adsorption conditions were tested, which proved that the LDH-NS/GO nanohybrids can be used in a wide temperature range for carbon dioxide capture, and the appropriate calcination temperature is 400 °C. Furthermore, the LDH-NS/GO nanohybrids also have a good multiple adsorption/desorption stability, which is vital for practical application.
