Production and characterisation of activated carbon and carbon nanotubes from potato peel waste and their application in heavy metal removal.

ABSTRACT: Herein, activated carbon (AC) and carbon nanotubes (CNTs) were synthesised from potato peel waste (PPW). Different ACs were synthesised via two activation steps: firstly, with phosphoric acid (designated PP) and then using potassium hydroxide (designated PK). The AC produced after the two activation steps showed a surface area as high as 833 m² g^-1 with a pore volume of 0.44 cm³ g^-1, where the raw material of PPW showed a surface area < 4 m² g^-1. This can help aid and facilitate the concept of the circular economy by effectively up-cycling and valorising waste lignocellulosic biomass such as potato peel waste to high surface area AC and subsequently, multi-walled carbon nanotubes (MWCNTs). Consequently, MWCNTs were prepared
