All Biomass-Based Solar-Driven Interfacial Evaporator for Efficient Seawater Desalination and Power Generation.

ABSTRACT: Solar-driven interfacial evaporation has emerged as a promising strategy to alleviate global water scarcity. However, most existing evaporators still depend on synthetic materials, raising concerns over their environmental impact. Herein, Fe³⁺-coordination-driven assembly of cellulose nanofiber (CNF)/Fe³⁺/lignosulfonate (LS) into photothermal layer (CFL) with a porous CNF/Fe³⁺ aerogel (CF) water transport channe, respectively, to construct a fully biomass-derived solar-driven interfacial evaporator. The results establish that Fe³⁺-LS coordination synergistically endows with the outstanding photothermal performance of the CFL hydrogel, achieving 95% full-spectrum solar absorption. The hydrated polymer network present in the CFL hydrogel can regula
