Graphene oxide (GO) and multi-walled carbon nanotubes (MWCNT) have been previously used 10 independently as active supports for Layered Double Hydroxides (LDH), and found to enhance the 11 intrinsic CO 2 sorption capacity of the adsorbents. However, the long-term stability of the materials 12 subjected to temperature-swing adsorption (TSA) cycles still requires improvement. In this contribution, 13GO and MWCNT are hybridized to produce mixed substrates with improved surface area and

“…It has been reported that significant performance enhancements of LDH‐derived MMOs in both organosulfur and CO 2 sorption can be obtained by dispersing them on high surface area materials, such as carbons. [ 28,33b,34 ] It has also been shown that graphene‐based powders (such as GO) provide particularly suitable supports due to matching morphology and surface charge between LDH and GO support. [ 28,34 ] However, there are no studies assessing the benefits of 3D‐structured macroscopic graphene supports, such as rGO aerogels, on the MMO performance in these important sorption applications.…”
