Synthesis and Characterization of Mesoporous Carbon Functionalized with Carboxylate Groups for a Promising Adsorbent
Mesoporous carbon material CMK-3 was successfully prepared by using mesoporous silica material SBA-15 as hard template and sucrose as carbon source through a nanocasting method.In order to improve the hydrophilic properties of the carbon materials,a large amount of carboxylic functional groups have been introduced upon the surface of carbon materials by oxidative treatment.Transmission electron microscopy (TEM) exhibit highly ordered mesostructure with 2-D hexagonal symmetry of our sample.An absorption assigned to the-COOH groups is clearly visible in Infrared spectra,suggesting the presence of carboxylic functional groups.Rhodamine B (Rh B) was selected as a model for determining the adsorption activity of the obtained material.This material exhibited a high adsorption capacity,and an extremely rapid adsorption rate.
