2D Materials-enhanced Nanocomposite Membranes For Catalytic Removal Of Contaminates From Wastewater

2D materials MXene, graphene oxide and MoS2 were employed in developing chitosan-based catalytic nanocomposite membranes for the removal of organic contaminants and heavy metals from wastewater. The defect sites on the MXene structure accelerated the decomposition of hydrogen peroxide, and generated reactive oxygen species (ROS), which oxidize organic contaminants and reduce heavy metals. An amphiphilic composite membrane was design and fabricated which not only has hydrophobic MoS2 nanoparticles for capturing the fine oil droplets, but also has hydrophilic cellulose acetate polymer for facilitating high water flux. Both membranes showed remarkable anti-fouling performance that ascribed from the catalytic activity of nanocomposite membranes.
