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

Published: Feb. 12, 2025

Abstract Combining interfacial solar steam evaporation with power generation to produce freshwater and electricity is an effective approach alleviating scarcity energy crises. However, constructing low‐cost, efficient integrated evaporator‐generator devices remains challenging, the synergistic mechanism underlying evaporation‐power co‐generation not yet well understood. Herein, low‐cost carbon foam‐based bifunctional evaporators that effectively achieve are designed. Carbon foam obtained from waste polyester using a ball‐milling‐assisted carbonization strategy. The evaporator demonstrates excellent water transport, outstanding sunlight absorption, low enthalpy. It achieves ultra‐high rate of 3.03 kg m −2 h −1 conversion efficiency 99.4%. Additionally, it exhibits continuous high voltage (0.33 V) current output (14.4 µA), surpassing performance state‐of‐the‐art materials‐based evaporators/generators. outcome molecular dynamics simulations stronger interaction surface functional groups in Na + than Cl − results formation flow potential, when exposed sunlight, further insights into generation. This study expands new path for sustainable co‐production by collecting natural single, devices.
