In this communication, Carbon aerogels were prepared by hydrothermal process using glucose as raw material and the structure and morphology were characterized by XRD, SEM, and IR. Methylene blue was removed by employing the as-prepared nano materials as adsorbent. The maximum adsorption capacity determined from the Langmuir adsorption isotherm was 819.67 mg.g-1 and adsorption kinetics and adsorption isotherms were also studied.
