Exploring Newly Designed Mn-MOF for Sustainable Energy Harvesting and Smart Parking System
Specifically designed functional metal–organic frameworks (MOFs) have emerged as promising materials for triboelectric nanogenerators (TENGs). However, a material for achieving high triboelectric effects and efficient output performance without using any commercial tribo active polymers is urgently needed. By designing MOFs using reticular chemistry, herein, a Mn-MOF named IITI-4 is explored. IITI-4 exhibits a high modulation chain-like structure to develop multiple nanotubular porous channels. The high porosity can hold charge and reduce the charge decay with a loss of only 4.8% confirmed via KPFM measurement. IITI-4 was explored in a TENG-based energy-harvesting device with the MOF as the active layer. The IITI-4 TENG device achieved an excellent voltage of 201.3 V. The IITI-4 TENG device showed excellent capability by powering low-power electronics. A smart parking system was developed using a IITI-4 TENG for monitoring the occupancy and vacancy of parking slots. Real-time results were displayed to alert personnel managing the smart parking system.
期刊介绍：
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times.
