摘要

In the present world, the high energy demand rapidly depletes existing fossilfuel reserves, urging the necessity to harvest energy from clean and renewableresources. In this study, the use of a triboelectric nanogenerator (TENG)is shown beyond the conventional practice of use in self-powered electronics,to the production of green hydrogen from renewable mechanical energy.For the first time the use of a magnetic covalent organic framework compositeas positive triboelectric material for a contact-separation mode TENG(CS-TENG) in which MXene incorporated polydimethylsiloxane (PDMS) filmserves as negative triboelectric material, is demonstrated. A facile way ofincorporating micropatterns on the surface of PDMS/MXene film is shownutilizing the advantages of 3D printing technology. The CS-TENG harvestsenergy from simple mechanical actions such as human handclapping andtoe-tapping. The energy from such low-scale mechanical actions is appliedfor water electrolysis. Scanning electrochemical microscopy is employed toconfirm the evolution of hydrogen and oxygen by the harvested electricalenergy from mechanical actions. This research is expected to pave the wayfor producing green hydrogen anywhere, by utilizing the mechanical energyfrom nature such as raindrops, wind, and the movement of vehicles.
