| Abstract: | Two microporous carbon molecular sieve(CMS)samples with different surface properties were obtained from a commercial CMS through deashing treatment(C1)and then oxidation(C2)by 30%H2O2 solution.Both the two samples were characterized by acidic/basic titration,N2 adsorption isothermal(BET),point of zero charge(pHPZC).Decomposition of H2O2 in dilute unbuffered solution was carried and the evolved oxygen was measured volumetrically.After oxidation,the surface acidity and total surface oxygen-containing groups i... |
