Liquefaction of Cellulose for Production of Advanced Porous Carbon Materials.

Cellulose is a renewable resource for the production of advanced carbonaceous materials for various applications. In addition to direct carbonization, attention has recently been paid to the preparation of porous carbons from liquid cellulose-based precursors. Possible pathways of cellulose conversion to a liquid state suitable for the preparation of porous carbons are summarized in this review.

The role of the oxygen functional groups in adsorption of copper (II) on carbon surface.

The effect of carbon surface oxidation on the adsorption of Cu(II) ions from aqueous solution was studied in order to explain the role of the oxygen functional groups in the binding of copper ions. Pristine carbonaceous adsorbent was oxidized to a various extent of oxygen uptake (Fenton-like oxidation < persulphate in HSO < HO in HNO). Equilibrium adsorption tests were performed in acetate buffer at pH ≈ 5.
