Copper oxide-loaded porous carbons (PCs) for elemental mercury adsorption were prepared. Copper oxides were loaded onto porous carbons by electroless plating method. Additionally, porous carbons were prepared from ion-exchangeable polymeric resin by a physical activation method flowed by oxidation. The microstructure of the copper oxide/PCs was characterized by XRD, and the formation of copper oxides after the electroless plating was confirmed by XPS. It was found that the presence of copper oxides significantly led to an increase in the elemental mercury adsorption capacity of the carbons. Copper oxide nanoparticles have electron-donor features, resulting in the enhancement of adsorption capacity of elemental mercury molecules, which have an electron acceptor feature. |
