Abstract
Droplets of ionic solutions sliding on two-dimensional (2D) materials induce an electrical current, which can be exploited to harvest the energy of raining. However, previously studied 2D materials generally suffer from poor scalability and low current. In this work, we demonstrate that a layered Ti3C2Tx MXene film generates the highest current among all pristine 2D materials ever reported. The film fabrication is highly scalable, which can be facilely spray-coated on construction materials including brick and wood, paving the way toward practical applications.
