Abstract:
Copper‐based metal–organic framework/graphene oxide (MOF‐199/GO) composites were prepared under hydrothermal conditions. The adsorption performances of the composites for CH 3 SCH 3 and CH 3 CH 2 SH removal under ambient conditions were evaluated. The materials were characterized by XRD, FTIR spectroscopy, nitrogen adsorption/desorption, scanning electron microscopy (SEM), and X‐ray photoelectron spectroscopy (XPS). The composites exhibit a unique layered structure. MGO‐1 with 5 % GO shows a higher surface area than that of pristine MOF‐199 owing to the creation of new pores between the MOF‐199 and GO units. MGO‐1 has the best adsorption capacities for CH 3 SCH 3 and CH 3 CH 2 SH, and the uptake reaches 6.12 and 4.31 %, respectively, because of the increased surface area and dispersive forces in the new pores. During the adsorption of CH 3 CH 2 SH, a chemical reaction results in the destruction of the MOF structure. However, reversible chemisorption was found for CH 3 SCH 3 removal, as testified by fixed‐bed regeneration. Multiple adsorption/regeneration cycles show that the MGO composites are promising adsorbents for CH 3 SCH 3 removal.
