Efficient Antibacterial Membrane based on Two-Dimensional Ti3C2Tx (MXene) Nanosheets

Abstract Advanced membranes that enable ultrafast water flux while demonstrating anti-biofouling characteristics can facilitate sustainable water/wastewater treatment processes. MXenes, two-dimensional (2D) metal carbides and nitrides, have attracted attention for applications in water/wastewater tr...
