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.
