Facile Preparation of MCM-41/Ag₂O Nanomaterials with High Iodide-Removal Efficiency.

ABSTRACT: The elimination of iodide (I^-) from water is a tough subject due to its low adsorption tendency and high mobility. In this work, MCM-41/Ag₂O nanomaterials were prepared, characterized, and employed to adsorb I^- from water. The Ag₂O nanoparticles were dispersed homogeneously in the pores or at the surface of the MCM-41 support, and the Ag₂O nanoparticles in the pores had small particles sizes due to the confinement of the mesoporous channel. The prepared MCM-41/Ag₂O nanomaterials exhibited a higher specific surface area than previously reported Ag₂O-based composites. The adsorption of I^- by the nanomaterials was able to reach equilibrium at 180 min. The MCM-41/Ag₂O nanomaterials showed a bette
