摘要：SummaryMetal-organic frameworks (MOFs) are multifunctional materials with a unique advantage of high porosity and surface area and size tunability and can be modified without altering the topology. The interesting and desirable properties of MOFs led to their exploration for the triboelectric nanogenerator. Herein, a biodegradable MOF MIL-88A for TENG (MIL-TENG) is reported. MIL-88A can be easily synthesized by coordinating iron chloride and fumaric acid in water, thus offering eco-friendly synthesis. Various materials are selected as opposite layers to MIL-88A to analyze triboelectric behavior and performance. The MIL-TENG exhibits an output trend of TENGEC < TENGKapton < TENGFEP. The MIL-88A and FEP generated an output voltage of 80 V and an output current of 2.2 μA. The surface potential measurement and electrical output trend suggest the positive triboelectric behavior of MIL-88A concerning FEP and Kapton. The utilization of biomechanical motions and numerous low-rating electronics powered via a capacitor are demonstrated.Graphical abstractDisplay OmittedHighlights•Biodegradable MIL-88A behave as positive material concerning FEP and Kapton•MIL-TENG produces an output of 80 V and 2.2 μA•MIL-TENG demonstrated for biomechanical energy harvesting•Numerous low-power electronics are powered using MIL-TENG via a capacitorInorganic Chemistry; Materials Science; Energy Materials
