文摘

Amine-rich polymeric nanofibers were hydrothermally synthesized by a simple polycondensation method using melamine, phloroglucinol, and formaldehyde as starting materials. The synthesized phloroglucinol–melamine–formaldehyde (PMF) polymeric nanofibers were characterized by various techniques, such as scanning electron microscope, transmission electron microscope, N₂ adsorption–desorption, Fourier transform infrared spectroscopy and ¹³C nuclear magnetic resonance, etc. Pure CO₂ gas adsorption on the as-prepared PMF nanofibers was investigated by the volumetric method. Breakthrough column experiments showed that CO₂–N₂ or CO₂–CH₄ mixtures could be separated on the PMF nanofibers. Additionally, the PMF polymeric fibers were carbonized, leading to nitrogen-rich carbon nanofibers, which exhibited an improved CO₂ adsorption capacity.
