Abstract：Usingtheisolutioegenerationmetod，elloehdrogelwasprepard.Underalkalieasaatalst，edrolyse sationratoftetraeortosilcate（EO）waontrolldoregulatetesefteprepaedSiparticles，floedyhooief cellulose and SiO 2 ，which was thenfreeze-driedtoobtainaSiO/celllosecompositeaerogel.Afterhydrophobic modification withalkylsiloxane，a superhydrophobic oleophilic SiO/cellulose composite aerogel was prepared.The results indicated successful SiO incorporation into the cellulose aerogel，and the prepared SiO/celulose composite aerogel had a porous structure.At apH value of 10 ！ SiO2 sphere had a size range of 5O～2O0 nm，and SiO2/cellulose composite aerogel had a static contact angle of 158.9° and a roll-off angle of 3.2° ，of which oil absorption capacity was 12.8 times its own weight.
