Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 27, 2025

Abstract Solar‐driven interfacial evaporation (SIE) emerge as a promising technology to mitigate the worldwide freshwater shortage and energy crisis. Carbon nanotubes (CNTs) are widely used for construction of hydrogel evaporators. Nevertheless, their performance is still restricted by poor dispersibility strong hydrophilicity. Even worse, agglomeration CNTs will diminish formation porous structures within hydrogels weaken water transportation, finally resulting in decreased efficiency. To address those issues, with improved hydrophilicity successfully achieved via metal‐phenolic coordination chemistry‐based engineering. The networks (MPN)‐coated further incorporated into poly(vinyl alcohol) hydrogel, synergistically realize superior photothermal molecule activation. In this way, robust solar evaporator hierarchical pores fabricated efficient mass which achieves rate 2.9 kg m −2 h −1 under 1 sun illumination while maintaining stable operation long‐term high‐salt environments. Actual outdoor experiments catalytic gel acrylamide confirm robustness these MPN‐coated CNT‐based devices SIE. It believed that study paves new avenue toward development carbon‐based hierarchically evaporators, evaporation.
