The effect of HCl treatment on the porous properties of carbon cryogels synthesized from resorcinol and formaldehyde (RF) is investigated in this work. The treated and untreated carbon cryogels were analyzed by nitrogen adsorption-desorption apparatus, the scanning electron microscope (SEM) and high performance liquid chromatograph (HPLC). The results show that the HCl treatment can enlarge the micropore diameter which is merit to the electric double layer capacitor, and it can broaden the mesopore diameter which is suitable in the mesoporous carbon support for catalysts. The micropore volume, the mesopore volume and the weight loss of the carbon cryogel can be changed insignificantly by the HCl treatment. Moreover the SEM images and the HPLC chromatograms support that the HCl treatment can promote the Ostwald ripening effect for the RF carbon cryogels.
