摘要

Abstract

Amine-functionalized mesoporous silica was prepared by using lauric acid and N-stearoyl-l-glutamic acid as structure directing agents via the S

-I

mechanism and applied to CO

adsorption at room temperature. With γ-aminopropyltriethoxysilane as co-structure directing agent and due to the direct electrostatic interaction with anionic surfactant

most of the amino groups were uniformly distributed at the inner surface of pores and the performance was stable. The amine-functionalized mesoporous silica was characterized by Fourier transform infrared spectrometer

X-ray diffraction

nitrogen physisorption and thermogravimetric analysis. The CO

adsorption capacity was measured by digital recording balance. At the room temperature and under the atmospheric pressure

the adsorption capacity of LAA-AMS-0.2 for CO

and N

is 1.40 mmol·g

-1

and 0.03 mmol·g

-1

respectively

indicating high separation coefficient of CO
