Abstract

Abstract: In this study, a novel composite Cu-BTC-(n)Br/MCFs was successfully synthesized by solvothermal method. The composites were characterized by XRD, N2 adsorption and desorption, SEM, FT-IR, TG, and water vapor adsorption technologies. Meanwhile, the CO2 adsorption isotherms were obtained using the static adsorption instrument which could be well fitted by the Langmuir-Freundlich model. The Cu-BTC-0.05Br/MCFs exhibited a good CO2 adsorption capacity of 2.44 mmol/g which was basically maintained after five adsorption-desorption cycles. More importantly, the Cu-BTC-0.05Br/MCFs also showed remarkable adsorption effectivity that was an increase of 8.7% than the Cu-BTC/MCFs at 35 °C and 1 bar after water treatment. The Cu-BTC-(n)Br/MCFs were promising candidate materials for effectively CO2 capture in practical application. Graphical Abstract: ga1 Highlights: Cu-BTC-(n)Br/MCFs composites were successfully synthesized for the first time. The Cu-BTC-0.05Br/MCFs exhibited a good CO2 adsorption capacity of 2.25 mmol/g that was an increase of 8.7% than the Cu-BTC/MCFs with water treatment. Cu-BTC-(n)Br/MCFs exhibited good hydrothermal stability and recycling performance.
