    This work explores the catalytic pyrolysis of biomass-derived residues, such as rice husks, eucalyptus leaves, and alkaline lignin, for the synthesis of nanocarbon materials with potential application in mercury removal from aqueous solutions. Two iron-based catalysts and different pyrolysis conditions were employed to obtain carbon nanotubes and nanosheets. The adsorption capacity for Hg(II) of the resulting nanocarbons and the effectiveness of reducing mercury concentration from water was determined. These results highlight the valorisation of biomass waste as a sustainable route for producing nanocarbons with adsorption applications.
