Abstract
Carbon nanomaterial has advanced tremendously over the past decades and is belong to the most competitive materials that will affect human life in the future. The renewable conversion from environmental friendly cellulosic biomass into solid carbon nanomaterials is of profound significance. In this article, the cordierite reinforced graphite nanocomposite synthesized through in-situ carbon-bed pyrolysis method is proposed. The microstructure and adsorption properties of as-prepared samples are characterized, it was found that the in situ prepared cordierite reinforced graphite nanocomposite was with a unique layered and porous structure. The adsorption properties of methylene blue onto composite were significantly enhanced by cordierite component, the equilibrium adsorption data well fit to the Langmuir equation together with maximum monolayer adsorption capacity of 988.928 mg/g, the kinetic adsorption data follows the pseudo-first-order kinetic model, the electrostatic and π-π stacking interactions mechanism also contributes to the adsorption.
