In situ decoration of Ag@exfoliated graphite composite catalyst for Fenton-like oxidation of methylene blue dye: kinetic and thermodynamic studies.

ABSTRACT: Amendable nanomaterials are preferred for wastewater remediation. Silver (Ag) and graphene materials have drawn significant consideration for wastewater treatment due to their good dispersibility in aqueous systems, biocompatibility, and catalytic activity. For this purpose, an easy-to-follow procedure has been developed to prepare exfoliated graphite (EG) involving a binary-component system composed of concentrated H₂SO₄ and (NH₄)₂S₂O₈. Afterwards, Ag@EG composite catalysts were prepared by in-situ decoration of silver nanoparticles (AgNPs) over EG by sonication. The prepared catalysts were investigated for methylene blue (MB) dye removal from wastewater using a homogeneous Fenton-like oxidation process (H₂O
