Abstract:In this paper, various amine-modified CO2 adsorbents were prepared by incorporating tetraethylenepenthamine (TEPA) onto SBA-15(P) by controlling dynamic impregnation process. The materials were characterized by X-ray diffraction (XRD), nitrogen adsorption/desorption, elemental analysis (EA) and Fourier transform infrared (FT-IR) experiments. Moreover, the adsorption capacities and cycle life were evaculated by CO2 temperature programmed desorption (CO2-TPD). Various characterization results indicate th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
