Preparation of metal-organic framework/attapulgite hybrid material for CO2 capture

A novel HKUST-1/attapulgite hybrid material was synthesized by in situ method for CO2 capture. The materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermo-gravimetric analysis (TGA), N2 adsorption-desorption isotherm and Fourier transform infrared spectroscopy (FT-IR). The characterizations showed that the incorporation of attapulgite did not change the crystalloid structure and the octahedron geometry of HKUST-1. The CO2 adsorption experiments showed an increase of 11.27% in CO2 adsorption capacity compared with that of HKUST-1. The excellent adsorption capacity and the low-cost raw material made the hybrid material had potential applications in the field of energy and environment.
