Solar-driven interfacial evaporation technology is regarded as a promising strategy for global freshwater shortage owing to its green and sustainable desalination process. Graphene aerogel (GA) widely utilized in the design of solar-driven steam generation systems due excellent photothermal conversion efficiency broad spectral absorption. Given significant impact hydrophilicity thermal insulation on performance evaporators, nitrogen doping graphene structure not only effectively enhances wettability but also allows moderate tuning conductivity, thereby optimizing overall evaporator. Therefore, oxide (GO) ethylenediamine were used prepare nitrogen-doped (NGA) via one-step hydrothermal method. Experimental investigations molecular dynamics (MD) simulations employed explore effects varying nitrogen-doping concentrations conductivity NGA. The results revealed that concentration increased, exhibited enhanced wettability, while initially decreased then increased. This phenomenon attributed fact improved can hinder heat convection, resulting reduced transfer efficiency. However, further enhancement reduces solid–liquid resistance, boosting performance. Consequently, NGA-2, with an optimal concentration, demonstrated superior performance, achieving high rate 1.64 kg m–2 h–1 outstanding 92.2% under one-sun irradiation. study highlights solar evaporators through synergistic mass transfer, underscoring their potential seawater applications.

The development of advanced membranes with switchable superwettability has attracted considerable attention for the efficient treatment oily wastewater. However, challenges persist in designing and fabricating such through straightforward methods. In this study, a novel strategy is presented to design superwettable based on micro/nano-structured porous surfaces surface chemical composition reorganization. A commercial amphiphilic polymer, polyamide-imide (Torlon), fabricated into symmetric membrane hierarchical structure using one-step non-solvent-induced phase separation method. By leveraging reorganization capability polymers hierarchically structure, resulting demonstrate exceptional superamphiphilicity air, underwater superoleophobicity, underoil superhydrophobicity. These properties enable ultrahigh permeance efficiency oil-in-water, water-in-oil, crude oil/water emulsions gravity-driven process, eliminating need external energy. Furthermore, exhibit excellent antifouling self-cleaning performance, maintaining stable operation over multiple cycles. This work provides an innovative scalable approach next-generation broad potential applications wastewater beyond.
