MXene-based (g-C₃N₄) nanosheet membranes for dye separation: g-C₃N₄ nanosheet membranes; separation performance of g-C₃N₄ membranes against different dye molecules. (a) Separation performance based on the thickness of the membranes; (b) against the diameter (size) of each probe molecule; (c) water permeance and zeta potential of the membrane in different pH environments; (d) water permeability based on variable pressure.
