Abstract
A method of adsorbing a dye from an aqueous solution including contacting a composition with the aqueous solution. At least a portion of the dye adsorbs to the composition. The composition includes biochar, cellulose nanocrystals, and a layered double hydroxide (LDH). The LDH includes Cu and Fe. Particles of the LDH and the biochar at least partially cover an outer surface of the cellulose nanocrystals.
