Silver Nanoparticles Supported onto TEMPO-Oxidized Cellulose Nanofibers for Promoting Cd²⁺ Cation Adsorption.

ABSTRACT: Nanocellulose constitutes a sustainable and biobased solution both as an efficient sorbent material for water treatment and as support for other inorganic nanomaterials with sorbent properties. Herein, we report the synthesis of a nanocomposite by deposition of in situ-generated silver nanoparticles (AgNPs) onto TEMPO-oxidized cellulose nanofibers (TOCNFs). Following an in-depth analytical investigation, we unveil for the first time the key role of AgNPs in enhancing the adsorption efficiency of TOCNF toward Cd²⁺ ions, chosen as model heavy metal contaminants. The obtained nanocomposite shows a value of Cd²⁺ sorption capacity at equilibrium from 150 mg L^-1 ion aqueous solutions of ∼116 mg g^-1 against the value of 78 mg g^-1 measu
