• •Cellulose based aerogels (CAGs) were successfully fabricated from waste newspaper.•Trimethylchlorosilane treated CAGs were rendered both hydrophobicity and oleophilicity.•The resultant CAGs exhibit outstanding adsorption ability to organic liquids and oils.•This CAGs showed comparable filtration capacity to HEPA membrane for the lampblack. In this study, the lightweight, hydrophobic and porous cellulose-based aerogels (CAGs) were synthesized through a freeze–drying process using waste newspaper as the only raw material. After crosslinking with glutaraldehyde and treatment with trimethylchlorosilane (TMCS) using a simple thermal chemical vapor deposition process, the resulting CAGs became hydrophobic and oleophilic. Furthermore, the as-prepared CAGs exhibited a low density (17.4–28.7mgcm−3) and mesoporous inner-structure. All these properties attributed the novel aerogel not only with a good adsorption capability of oils and organic solvents, including kerosene, nitrobenzene, and chloroform, but also an excellent filtration capacity of lampblack.
