A Large‐Area Graphene‐Based Composite Paper for Efficient Gold Extraction From E‐Waste and Its Reuse
EcoMat, Volume 7, Issue 5, May 2025.A composite gold adsorbent was developed by assembling reduced graphene oxide (rGO) onto cellulose paper. The resulting material offers scalability and eliminates the need for complex post‐adsorption separation processes. With its large surface area, mechanical robustness, and high efficiency, the composite demonstrates exceptional areal gold ...
