Thermal conversion of alkaline lignin and its structured derivatives to porous carbonized materials
چکیده انگلیسی

Alkaline lignin was thermally converted to microporous carbon in ca. 50% yield by heating up from room temperature to 900 °C without activation process under flowing of an argon gas. The carbonized material prepared by heating up conditions of 1 °C min−1 showed 530 m2/g of the Brunauer–Emmett–Teller (BET) specific surface area, which increased to 740 m2/g after washing with water. Furthermore, alkaline lignin derivatives were structured as micron scale particles by micelle formation and polymer gelation techniques. Carbonization of the structured lignins could afford high porous materials having BET surface areas above 1000 m2/g without surface activation processes.

Alkaline lignin and structured lignin derivatives were thermally converted to micropore-based porous carbons.Figure optionsDownload as PowerPoint slide
