Cellulose/carrageenan/TiO 2 nanocomposites were simply prepared by the co-dissolution of cellulose and carrageenan, and the dispersion of TiO 2 in 1-ethyl-3- methylimidazolium acetate, followed by reconstitution with anti-solvents. The cellulose/carrageenan/TiO 2 composite showed a much higher adsorption capacity for methylene blue (MB) than the cellulose and cellulose/TiO 2 composite. The cellulose/carrageenan/TiO 2 composite also degraded MB more efficiently in aqueous solution than the cellulose/ TiO 2 composite. The MB adsorption capacity of the cellulose/carrageenan/TiO 2 composite increased linearly with increasing carrageenan content in the composites.
