Solar-driven interfacial evaporation harnessing solar energy on a water surface provides sustainable and economic means to efficiently capture freshwater from nontraditional sources. Endowed with hierarchical porous structure mechanical stability, wood-based evaporators represent renewable alternative petroleum-based materials. Nonetheless, incidental inferiorities of low rate weak strength are challenging overcome. Herein, we propose the usage chemically stable coordination polymers (Ni-dithiooxamidato, Ni-DTA) as hydrophilic photothermal nanomaterials for molecular design robust improved performance. In situ synthesis Ni-DTA onto channel wall balsawood sufficient domains that localize converted facilitated evaporation. A rational control methanol/dimethylformamide ratios enables coexistence 1D-nanofibers 0D-nanoparticles, endowing Balsa-NiDTA high 2.75 kg m-2 h-1 an efficiency 82% under one-sun illumination. Experimental simulation results reveal strong hydration ability decrease equivalent enthalpy induced by decreased H-bonding density molecules near interface. The evaporator showed chemical mainly due Ni-S/Ni-N bonds superior cellulose affinity Ni-DTA. Furthermore, shows excellent antibacterial activity oil-fouling propensity. This work presents facile mild strategy evaporators, contributing highly efficient desalination harsh conditions.

Abstract To alleviate the severe water crisis, an interfacial solar evaporator provides a promising method to produce freshwater. Although many superior evaporators present high evaporation rates by reducing enthalpy, adapting sustainable materials construct high‐efficiency remains challenging. Herein, inspired corncob pith's structure and functional groups, interconnected porous cellulose hydrogel is proposed crosslinking hydroxypropyl cellulose. Benefiting from abundant hydroxy group, pith/carbon nanotubes (CNTs) hydrogel/CNTs show low enthalpy of 880.5 ± 42.1 1280.7 57.8 J g −1 due reduced hydrogen bond numbers between molecules enable 3.06 2.56 kg m −2 h , respectively. Moreover, purification performance for seawater sewage, excellent anti‐biological fouling properties under light irradiation. It anticipated that bionic strategy would provide in‐depth understanding designing next‐generation in framework dual‐carbon concept.
