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 V_oc and I_sc 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 V_oc, respectively. In conclusion, this work offers a high-efficiency and eco-friendly way for the sustainable utilization of seawater resources.

离子泵启发的仿生界面蒸发平台，用于同时进行海水淡化、铀提取和发电

为了加快实现可持续发展目标（SDGs），我们在此开发了一种受离子泵启发的仿生界面蒸发平台（IBIP）。这种创新平台集海水淡化、发电和铀提取于一体。生物炭掺杂的海藻酸钠水凝胶被用来验证 IBIP 的功效。在 1 个太阳下进行的长期试验中，IBIP 保持了 1.80 kg m h 的稳定蒸发率，并在 48 小时内在真实海水中实现了超过 80 % 的稳定铀吸附率。此外，IBIP 还显示出更强的电力输出，V 值和 I 值分别达到 0.9 V 和 14.0 μA。通过构建三维结构，IBIP 在 1 个太阳下的性能大幅提升，蒸发率达到 4.3 kg m h，铀萃取能力达到 168.1 mg g，V 值达到 1.02 V。总之，这项工作为海水资源的可持续利用提供了一种高效、环保的途径。
