Growth in population and increased environmental awareness demand the emergence of new energy sources with low environmental impact. Lignocellulosic biomass is mainly composed of cellulose, lignin, and hemicellulose. These materials have been used in the energy industry for the production of biofuels as an eco-friendly alternative to fossil fuels. However, their use in the fabrication of small electronic devices is still under development. Lignocellulose-based triboelectric nanogenerators (LC-TENGs) have emerged as an eco-friendly alternative to conventional batteries, which are mainly composed of harmful and non-degradable materials. These LC-TENGs use lignocellulose-based components, which serve as electrodes or triboelectric active materials. These materials can be derived from bulk materials such as wood, seeds, or leaves, or they can be derived from waste materials from the timber industry, agriculture, or recycled urban materials. LC-TENG devices represent an eco-friendly, low-cost, and effective mechanism for harvesting environmental mechanical energy to generate electricity, enabling the development of self-powered devices and sensors. In this study, a comprehensive review of lignocellulosic-based materials was conducted to highlight their use as both electrodes and triboelectric active surfaces in the development of novel eco-friendly triboelectric nano-generators (LC-TENGs). The composition of lignocellulose and the classification and applications of LC-TENGs are discussed.
人口增长和增强的环境意识要求开发具有低环境影响的新能源。木质纤维素生物质主要由纤维素、木质素和半纤维素组成。这些材料已被用于能源行业，以生产生物燃料，作为对化石燃料的环保替代品。然而，它们在小型电子设备制造中的应用仍在开发中。基于木质纤维素的摩擦纳米发电机（LC-TENG）已成为传统电池的环保替代品，传统电池主要由有害和不可降解的材料组成。这些 LC-TENG 使用基于木质纤维素的组件作为电极或摩擦电活性材料。这些材料可以源自木材、种子或叶子等大块材料，也可以源自木材工业、农业或回收城市材料中的废物材料。LC-TENG 设备代表了一种环保、低成本且有效的环境机械能收集发电机制，可用于开发自供电设备和传感器。在这项研究中，对基于木质纤维素的材料进行了全面综述，以强调它们在新型环保摩擦纳米发电机（LC-TENG）的开发中作为电极和摩擦电活性表面的用途。讨论了木质纤维素的组成以及 LC-TENG 的分类和应用。
