Abstract

To accelerate progress toward the Sustainable Development Goals (SDGs), here we develop an ion pump-inspired biomimetic interfacial evaporation platform (IBIP). Such an innovative platform integrates seawater desalination, electricity generation, and uranium extraction. A biochar-doped sodium alginate hydrogel is used to validate the IBIP’s efficacy. In long-term trials under 1 sun, IBIP maintains a stable evaporation rate of 1.80 kg m−2 h−1 and achieves a consistent uranium adsorption ratio exceeding 80 % within 48 h in real seawater. Additionally, the IBIP demonstrates an enhanced electricity output, with Voc and Isc reaching 0.9 V and 14.0 μA, respectively. By constructing a 3D structure, the IBIP’s performance under 1 sun significantly escalates to 4.3 kg m−2 h−1 for evaporation rate, 168.1 mg g−1 for uranium extraction capacity, and 1.02 V for Voc, respectively. In conclusion, this work offers a high-efficiency and eco-friendly way for the sustainable utilization of seawater resources.
