The continuous exploration of clean‐energy technology is critical for the sustainable development of society. The recent work on the electric energy harvesting from water evaporation has made a significant contribution to the utilization of clean energy for self‐powering systems. Here, a novel metal–organic‐framework‐based hybrid nanomaterial is delicately designed and synthesized by the growth of UIO‐66 nanoparticles on 2D AlOOH nanoflakes. Due to the combined merits from the 2D morphology, which is inherited from the AlOOH nanoflakes, and the high surface potential, which originates from the UIO‐66 nanoparticles, the device made of the AlOOH/UIO‐66 hybrid nanomaterials can harvest electric energy from natural water evaporation. An open‐circuit voltage of 1.63 ± 0.10 V can be achieved on the prototype devices made of the hybrid nanomaterial. As a proof‐of‐concept application, a small electric appliance, e.g., a digital calculator, is powered up by a 3 × 3 device array connected in a combined series–parallel configuration.

直接从水蒸发中收集电能的基于MOF的混合纳米材料的合理设计。

不断探索清洁能源技术对于社会的可持续发展至关重要。最近有关从水蒸发中收集电能的工作对为自供电系统利用清洁能源做出了重大贡献。在这里，通过在二维AlOOH纳米薄片上生长UIO-66纳米颗粒，精心设计和合成了一种新型的基于金属-有机-框架的杂化纳米材料。由于从AlOOH纳米薄片继承的2D形态的综合优点以及源自UIO-66纳米颗粒的高表面电势，由AlOOH / UIO-66混合纳米材料制成的设备可以从中收集电能自然水蒸发。由混合纳米材料制成的原型设备可以实现1.63±0.10 V的开路电压。× 3设备阵列以串联-并联组合方式连接。
