Conversion of sustainable lignocellulosic biomass of sorghum stalks to ultra-high surface area nanostructured phosphorous doped carbons for efficient adsorption of cationic dyes.

Biomass-based functional materials are known as versatile and cost-effective sources for the formation of different advanced nanocarbon materials. Sorghum stalks biomass is a main residual lignocellulosic agricultural material that produces huge amounts after harvesting of sorghum grains. However, Sorghum stalks biomass material has low density, large specific volume, and no nutritional value, therefore actions are required for its valorization.
