Nanochannel membranes are currently being employed for selective ion transport and salinity gradient energy capture. However, the poor functionality of nanochannel unfavorable influence multivalent cations result in low conversion efficiency, limiting performance membranes. Herein, multicomponent nacre-like heterogeneous nanochannels composed carboxymethyl chitosan (CMC)-intercalated composite two-dimensional (2D) GO, C3N4 nanosheets, polyethylene terephthalate (PET) channels developed using an interfacial assembly strategy. Benefiting from asymmetric structure, membrane achieves enhanced diffusion unidirectional behaviors. Subsequently, a high power density 8.46 W/m2 is achieved artificial seawater river water by membrane. Notably, introduction CMC into 2D lamellar endows with outstanding sieving performance, thereby mitigating divalent on conversion, reducing it 32.08% to 19.85%. Furthermore, exhibits sensitive stable light-responsive behavior, profiting light sensitivity GO improvement 11.29% can be accomplished irradiation. This work proposes idea design multifunctional achieve highly efficient conversion.
