Ultrathin Graphene Oxide-Based Nanocomposite Membranes for Water Purification
Two-dimensional graphene oxide (GO)-based lamellar membranes have been widely developed for desalination, water purification, gas separation, and pervaporation. However, membranes with a well-organized multilayer structure and controlled pore size remain a challenge. Herein, an easy and efficient me...

| description | Two-dimensional graphene oxide (GO)-based lamellar membranes have been widely developed for desalination, water purification, gas separation, and pervaporation. However, membranes with a well-organized multilayer structure and controlled pore size remain a challenge. Herein, an easy and efficient method is used to fabricate MoO<sub>2</sub>@GO and WO<sub>3</sub>@GO nanocomposite membranes with controlled structure and interlayer spacing. Such membranes show good separation for salt and heavy metal ions due to the intensive stacking interaction and electrostatic attraction. The as-prepared composite membranes showed high rejection rates (˃70%) toward small metal ions such as sodium (Na<sup>+</sup>) and magnesium (Mg<sup>2+</sup>) ions. In addition, both membranes also showed high rejection rates ˃99% for nickel (Ni<sup>2+</sup>) and lead (Pb<sup>2+</sup>) ions with good water permeability of 275 ± 10 L m<sup>−2</sup> h<sup>−1</sup> bar<sup>−1</sup>. We believe that our fabricated membranes will have a bright future in next generation desalination and water purification membranes. |
