Abstract

Abstract : Novel GO–ZIF-8 composites synthesized via controlled in situ method exhibit enhanced CO2 uptake capacity due to the synergistic effect. Abstract : A simple and controlled in situ synthesis method has been successfully used to produce graphene oxide/ZIF-8 composites from aqueous ammonia solution. A series of characterization techniques confirm the formation of strong interactions between ZIF-8 and graphene oxide in the synthesized composites. The crystal sizes of ZIF-8 and the textual properties of the composites can be tuned by the variable graphene oxide contents. The in situ synthesized composites exhibit enhanced CO2 adsorption energy and significant CO2 uptake capacity due to the synergistic effect between graphene oxide and ZIF-8. The synergistic interactions of ZIFs and graphene oxide may offer a new approach to produce novel graphene oxide/ZIFs composites for diverse applications.
