Recent advances in water-induced electricity generation based on 2D materials: A review

Two-dimensional (2D) materials with unique physical and chemical properties have attracted tremendous attentions for energy conversion applications (e.g., solar cells) in recent years. However, the periodic solar radiation somehow limits the widespread use of solar energy. Analogous to solar irradiation, water can also be found on Earth as a natural resource. Wherein, the presence of water is less restricted by the environmental conditions since it could exist in diverse forms. Therefore, harvesting green energy from water is a promising alternative to traditional energy conversion technologies. In this review, we have summarized the recent progress of water-induced electricity generation based on 2D materials. Starting with descriptions of the mechanisms proposed so far, four categories of water-induced electricity are discussed, which are across the droplet, flow, evaporation, and moisture. This review concludes with a perspective on current challenges and future directions for electricity generation from water.

Automated summary

This review summarizes the recent progress in water-induced electricity generation based on 2D materials, including four categories: droplet, flow, evaporation, and moisture. Water, as a natural resource, holds great potential as an alternative to traditional energy conversion technologies.
