Use of the membrane requires the Cu-TCPP material itself and ionic solution conditions for transport measurements. Light-responsive operation additionally requires illumination, including natural sunlight according to the abstract.; requires a Cu-TCPP two-dimensional membrane; light-responsive operation depends on the photothermal property of Cu-TCPP; highest reported performance in the abstract involves combining solar energy with a salinity gradient
The abstract does not show that the membrane solves all selectivity, stability, scalability, or manufacturing questions. It also does not provide detailed operating limits or long-term durability data.; ionic selectivity is discussed as a field-wide challenge, but the abstract does not quantify selectivity for this membrane

Comparisons
Source-stated alternatives
The abstract compares the membrane against state-of-the-art nanochannel membranes in general rather than naming a single direct alternative. The web summary also notes related comparator materials such as MXene and van der Waals heterostructure membranes, but the abstract itself does not benchmark them directly.
