Adsorption of CO2 on Activated Carbons Prepared by Chemical Activation with Cupric Nitrate
ACS Omega, 2020 Activated carbons were prepared from a lignocellulosic material, African palm shells (Elaeis guineensis), by chemical impregnation of the precursor with solutions of 1–7% w/v Cu(NO3)2 at five different concentrations.

Production and applications of activated carbons as adsorbents from olive stones
Biomass Conversion and Biorefinery, 2019 Olive stones have been widely used as a renewable energy biowaste source. As they are rich in elemental carbon (40–45 wt%), much research focussed on effectively converting olive stones, as precursors, into activated carbon adsorbents.
