The escalating energy and environmental challenges have catalyzed a global shift toward seeking more sustainable, economical, and eco-friendly energy solutions. Water, capturing 35% of the Earth's solar energy, represents a vast reservoir of clean energy. However, current industrial capabilities harness only a fraction of the energy within the hydrological cycle. The past decade has seen rapid advancements in nanoscience and nanomaterials leading to a comprehensive exploration of liquid-solid triboelectrification as a low-carbon, efficient method for water energy harvesting. This review explores two fundamental principle models involved in liquid-solid triboelectrification. On the basis of these models, two distinct types of water energy harvesting devices, including droplet-based nanogenerators and water evaporation-induced nanogenerators, are summarized from their working principles, recent developments, materials, structures, and performance optimization techniques. Additionally, the applications of these nanogenerators in energy harvesting, self-powered sensing, and healthcare are also discussed. Ultimately, the challenges and future prospects of liquid-solid triboelectrification are further explored.
不断升级的能源和环境挑战促使全球转向寻求更可持续、经济且环保的能源解决方案。水捕获了地球35%的太阳能，是一个巨大的清洁能源库。然而，目前的工业能力仅利用了水文循环中一小部分能量。在过去十年中，纳米科学和纳米材料取得了快速进展，促使人们全面探索液-固摩擦起电，将其作为一种低碳、高效的水能收集方法。本文综述探讨了液-固摩擦起电所涉及的两种基本原理模型。基于这些模型，从工作原理、最新进展、材料、结构和性能优化技术等方面总结了两种不同类型的水能收集装置，包括基于水滴的纳米发电机和水蒸发诱导纳米发电机。此外，还讨论了这些纳米发电机在能量收集、自供电传感和医疗保健方面的应用。最后，进一步探讨了液-固摩擦起电面临的挑战和未来前景。
