As water scarcity becomes an increasingly pressing issue, innovative solutions like atmospheric water harvesting (AWH) are being explored to provide sustainable access to fresh water. Dr Chinmoy Das, Assistant Professor from the Department of Chemistry and his research scholar Mr Sushant Wakekar have in their research paper titled, “Deciphering the functions of Metal-Organic Frameworks and their derived composites towards Atmospheric Water Harvesting: A comprehensive Review” analysed the crucial role of metal-organic frameworks (MOFs) and their composites in enhancing the efficiency of AWH systems.
Abstract
To address water scarcity globally, recently atmospheric water harvesting (AWH) has emerged as an intriguing and sustainable solution. This comprehensive review critically investigates how diversity in metal-organic frameworks (MOFs) and their composite materials shapes the effectiveness and practicality of AWH technologies. These materials range from pristine MOFs to functionalized MOFs-based composites to attain the sophisticated hydrophilic behavior to perform as water harvesters. The multifaceted effects of MOFs and their composite materials on the kinetics of sorption and condensation, the feasibility of water uptake and release, the overall performance of the materials, the theoretical understanding of water uptake, and various instrumentation techniques have been demonstrated in this comprehensive review. It contributes to the ongoing discourse on sustainable water sourcing by emphasizing the pivotal role of materials diversity in shaping the future of AWH technologies.
Explanation of Research in layperson’s terms:
This review article explains how AWH technology, which captures water from the air, could provide sustainable solutions for water scarcity. We focus on advanced materials called MOFs and their ability to improve AWH efficiency. By analyzing different types of MOFs and MOF-based composites, we explore how they enhance water absorption and release, potentially making AWH more practical and effective for real-world use.
Practical/Social Implications of the Research:
This technology could have far-reaching social impacts by offering a reliable water source for communities in arid or remote areas, reducing reliance on traditional, often costly water sources, and strengthening resilience to climate change.
Future Research Plans:
To design and synthesis a material which can work with a minimum relative humidity (%RH) and design a suitable prototype for it.
