Porous Ti₃C₂T_x MXene Membranes for Highly Efficient Salinity Gradient Energy Harvesting.

ABSTRACT: Extracting osmotic energy through nanoporous membranes is an efficient way to harvest renewable and sustainable energy using the salinity gradient between seawater and river water. Despite recent advances of nanopore-based membranes, which have revitalized the prospect of blue energy, their energy conversion is hampered by nanomembrane issues such as high internal resistance or low selectivity. Herein, we report a lamellar-structured membrane made of nanoporous Ti₃C₂T_x MXene sheets, exhibiting simultaneous enhancement in permeability and ion selectivity beyond their inherent trade-off. The perforated nanopores formed by facile H₂SO₄ oxidation of the sheets act as a network of cation channels that interconnects interplanar nanoca
