Abstract Nanochannel membranes have demonstrated remarkable potential for osmotic energy harvesting; however, their efficiency in practical high-salinity systems is hindered by reduced ion selectivity. Here, we propose a dual-separation transport strategy constructing two-dimensional (2D) vermiculite (VMT)-based heterogeneous nanofluidic system via an eco-friendly and scalable method. The cations are initially separated enriched micropores of substrates during the transmembrane diffusion, followed secondary precise sieving ultra-thin VMT laminates with high flux. Resultantly, our demonstrates efficient harvesting performance, especially hypersaline environment. Notably, achieve maximum power density 33.76 W m −2 , 6.2-fold improvement ten-fold increase salinity gradient, surpassing state-of-the-art nanochannel under challenging conditions. Additionally, confirm generation using various natural salt-lake brines, achieving 25.9 . This work triggers hopes blue conversion advanced nanoarchitecture.

Abstract Nanofluidic membranes offer exceptional promise for osmotic energy conversion, but the challenge of balancing ionic selectivity and permeability persists. Here, we present a bionic nanofluidic system based on two-dimensional (2D) copper tetra-(4-carboxyphenyl) porphyrin framework (Cu-TCPP). The inherent nanoporous structure horizontal interlayer channels endow Cu-TCPP membrane with ultrahigh ion allow power density 16.64 W m −2 , surpassing state of-the-art nanochannel membranes. Moreover, leveraging photo-thermal property Cu-TCPP, light-controlled active transport is realized even under natural sunlight. By combining solar salinity gradient, driving force reinforced, leading to further improvements in conversion performance. Notably, light could eliminate need achieving 0.82 symmetric solution system. Our work introduces new perspective developing advanced solar/ionic extends concept notion energy.
