Harnessing Natural Evaporation for Electricity Generation using MOF ‐Based Nanochannels

This work studies using nanochannels and the metal –organic framework MOF-801 to capture thermal energy from water evaporation in the environment and convert it into electrical power. MOF-801 enhances output with a 2.2 V open circuit voltage and 1.9 µA short circuit current. This evaporation-driven process provides an environmentally friendly w ay to generate power from water, heat, and light anywhere without external dependencies. AbstractFunctionalized nanochannels can convert environmental thermal energy into electrical energy by driving water evaporation. This process involves the interaction between the solid –liquid interface and the natural water evaporation. The evaporation-driven water potential effect is a novel green environmental energy capture technology that has a wide range of applications and does not depend on geographical location or environmental conditions, it can generate power as long as there is water, light, and heat. However, suitable materials and structures are needed to harness this natural process for power generation. MOF materials are an emerging field for water evaporation power generation, but there are still many challenges to overcome. This work uses MOF-801, which h as high porosity, charged surface, and hydrophilicity, to enhance the output performance of evaporation-driven power generation. It can produce an open circuit voltage of ≈2.2 V and a short circuit current of ≈1.9 µA. This work has a simple structure, easy preparat...
