Preparation and characterization of cellulose-based microporous carbon materials

Cellulose-based carbon adsorbents (RCMs) were fabricated via chemical activation with cellulose as the raw material and rubidium chloride (RbCl) as the activator. The microstructure and physicochemical properties of the as-prepared activated carbon were systematically investigated. A series of characterization techniques, including BET, SEM, XPS, XRD, Raman spectroscopy, and FT-IR spectroscopy, were employed to verify that RbCl exhibits favorable activation performance toward cellulose.
