Abstract
Abstract: In the present work, a novel carbon nanomaterial decorated with metal nanoparticles was prepared from banana leaf. An eco-friendly, carbon neutral with a high-cost efficiency quotient substance. The precursor, banana leaf was pyrolyzed in an inert atmosphere and activated by using alkali solution. It was then decorated with copper nanoparticles to obtain the final product. BET analysis revealed its significant specific surface area. The synergic effect of high surface area and nanometal decoration makes this carbon nanomaterial suitable for removal of Pb, Co and Cr toxic metal ions. It is very effective even when the concentration of metal ions is very low. Characterization of nanomaterials was carried out by SEM, HRTEM and XRD. The effect of pH on removal of toxic metal ions was also studied.
