Turing-type nanochannel membranes with extrinsic ion transport pathways for high-efficiency osmotic energy harvesting

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Nov. 26, 2024

Two-dimensional (2D) nanofluidic channels with confined transport pathways and abundant surface functional groups have been extensively investigated to achieve osmotic energy harvesting. However, solely relying on intrinsic interlayer results in insufficient permeability, thereby limiting the output power densities, which poses a significant challenge widespread application of these materials. Herein, we present nanoconfined sacrificial template (NST) strategy create crafted channel structure, termed as Turing-type nanochannels, within membrane. Extrinsic interlaced are formed between lamellae using copper hydroxide nanowires templates. These nanochannels significantly increase areas, resulting 23% enhancement ionic current while maintaining cation selectivity 0.91. The density nanochannel membrane increases from 3.9 5.9 W m−2 remains stable for at least 120 hours. This exhibits enhanced applicability real saltwater environments across China, achieving densities 7.7 natural seawater 9.8 salt-lake brine. work demonstrates promising potential Turing-channel design conversion field.
