Abstract
- The valorization of abundant agrowastes into chemicals and advanced materials is of key importance in the context of the circular bioeconomy and biorefinery. Herein, we report the ionothermal carbonization (ITC) of sugarcane bagasse, a fibrous residue made of lignocellulose, to engineer advanced carbonaceous materials, namely ionochars. We prepared a series of imidazolium tetrachloroferrate ionic liquids (IL) bearing modular substituents, e.g., alkyl chains with different lengths or benzyl groups. The effect of the cation on both textural and morphological properties is highlighted. Ionochars with high specific surface area (up to 800 m<superscript>2</superscript> g<superscript>−1</superscript>), tuneable pore volume (up to 0.8 cm<superscript>3</superscript> g<superscript>−1</superscript>), singular nanostructures and adjustable CO<subscript>2</subscript> uptake/retention were obtained.
