In this work, we have developed a highly efficient approach to fabricating graphene oxide (GO) functionalized with melamine molecule by chemical crosslinking. The melamine-functionalized graphene oxide (MEL-GO) was characterized by FT-IR, Raman, XRD TGA, XPS, SEM and TEM. Using monoethanolamine (MEA) aqueous solution as the basic absorbent, The absorbance performance of CO2 in the (MEL-GO)+MEA-FH2O solid-liquid hybrid absorbent for different mass concentrations of MEL-GO in 30 wt% MEA aqueous solution was investigated. The solubility of CO2 in (MEL-GO)+MEA+H2O absorbents is much larger than that in 30 wt% MEA aqueous solution. Moreover, when the partial pressure of CO2 continues to go up, the solubility of CO2 was obviously increased with increasing mass concentrations of MEL-GO. The results suggest that MEL-GO is beneficial to enhance the solubility of CO2 in MEA aqueous solution. (C) 2017 Elsevier B.V. All rights reserved.
