The adsorption-desorption isotherms of N2 at 77K on the graphite samples, which had been obtained through burning off a natural graphite with O2-H2O gas mixture, were measured volumetrically. And at the time the SEM observation for the samples were carried out. As a result, the basal plane were so eroded in the burning-off process that many holes were formed there. Both untreated graphite and the 20%-burnt-off one gave the similar adsorption isotherms of Type Ⅱ which have the Joyner-Emmett step near the relative pressure of 0.4, while the shape of the isotherm on the 53%-burnt-off graphite looks stepwise. The causes of this phenomenon were discussed in this paper.
