Abstract

Hydro-electric nanotechnology is touted as a promising next-generation renewable energy system because it employs environmentally-friendly and abundant water as an energy resource for producing electricity efficiently. However, the conventional hydro-electric nanogenerators have some limitations, such as difficulty in continuous and artificial induction of water stream and a low level of energy production for practical use. In this study, we devised a sustainable water harvesting and electrical energy generation system to overcome the limitations of conventional renewable energy. The system was successfully achieved with two distinctive metal-organic frameworks (MOFs), that are, an amine functionalized Zr-based MOF (UiO-66-NH₂) particles for atmospheric water harvesting, and a highly conductive Ni₃(HITP)₂ (HITP = 2,3,6,7,10,11-hexaiminotriphenylene) MOF-grown cotton-fabric for producing electrical energy. The environmentally responsive UiO-66-NH₂ harvests water from ambient air and the condensed water spontaneously produces electrical potential between wet- and dry-Ni₃(HITP)₂, resulting in electrical energy generation with a maximum power and energy densities of 2.6 μW/cm³ and 1.1 mJ/cm³, respectively. Our novel hybrid concept integrating water harvesting and energy generation systems can pave the way for realizing a hydro-electric nanogenerator as a next-generation energy harvesting system in the near future.

利用双mof系统通过大气水收集实现可持续电能收集

水力发电纳米技术利用环境友好且丰富的水作为有效发电的能源，被吹捧为有前途的下一代可再生能源系统。然而，传统的水力纳米发电机存在着一些局限性，如难以连续人工诱导水流，实际使用的能量产生水平低。在这项研究中，我们设计了一个可持续的集水和发电系统，以克服传统可再生能源的局限性。该系统成功实现了两种不同的金属有机框架（MOF），即胺功能化的zr基MOF （uui -66- nh2）颗粒用于大气水收集，以及高导电性的Ni3(HITP)2 （HITP = 2,3,6,7,10,11-己胺基三苯）MOF生长的棉织物用于产生电能。具有环境响应性的UiO-66-NH2从周围空气中收集水分，凝结水自发产生干湿ni3 (HITP)2之间的电势，产生最大功率和能量密度分别为2.6 μW/cm3和1.1 mJ/cm3的电能。我们的新混合概念集成了水收集和能量产生系统，为在不久的将来实现下一代能量收集系统的水电纳米发电机铺平了道路。

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
