“…The modied cellulose and cotton show higher negative triboelectricity than PI. However, the LCNF reported by Tanguy et al 171 is a naturally negative triboelectric material, and its output performance in a comparison experiment even exceeded that of an articially synthesized highly negative triboelectric material, PTFE. Although many research studies related to TENGs based on natural materials have been reported, there are various challenges remaining in this arena in terms of materials selection and generation performance improvement.…”

“…A recent study by Tanguy et al confirmed that natural materials from bark could be used in a tribonegative layer without modification. 171 More exploration is thus needed to develop natural materials that can be directly used as a tribonegative layer in TENGs. Meanwhile, natural materials with strong electron-withdrawing functional groups (–NO 2 , –CN, –F, etc. )…”

Lignocellulose nanopaper (LNP) assembled from lignocellulose nanofibrils (LCNFs) is an emerging eco-friendly structural material applicable to a variety of fields. Lignin serves as a crucial functional component in the LNP matrix; however, it negatively affects the interfacial hydrogen-bonding behaviors among LCNFs and consequently the inferior mechanical performance of LNP. In this study, a mild ozone-oxidation strategy was used to modify lignin macromolecules in situ without significant degradation of carbohydrate polymers (i.e., cellulose and hemicellulose) in LCNFs whereupon the interfacial hydrogen-bond energy was dramatically improved in the assembly and deformation process of LNP as validated by molecular dynamics simulation. Consequently, the lignin-modified LNP exhibited significantly enhanced tensile strength (from 83 to 140 MPa) and toughness (from 1.9 to 7.1 J/m 3 ), which even surpassed those of conventional cellulose nanopaper. Benefiting from the well-preserved lignocellulosic structure, lignin-modified LNP maintained its inherent favorable water and thermal stability and intriguing optical performance, which supported our developed LNP to be a multifunctional structural material for diversified fields, for example, flexible electronic applications. Additionally, the estimated production cost for our developed LNP was approximately half of that for conventional cellulose nanopaper due to its significantly lower resource inputs such as the material, water, and energy. Overall, our study provides a site-specific macromolecular modulation strategy for the economically and environmentally feasible fabrication of highperformance lignocellulosic nanomaterials toward advanced structural applications.

Triboelectric nanogenerator (TENG), an emerging energy conversion technology, offers innovative pathways for energy harvesting and self‐powered sensing. To achieve superior performance, researchers commonly employ substantial quantities of original or treated polymers, resulting in high energy and precise sensing. Nevertheless, the sustainable development of TENGs faces significant challenges related to environmental compatibility, pollution hazards, and high production and disposal costs. To address this issue, numerous green materials for diverse TENGs are introduced and advanced. These materials may encompass natural resources, household waste, and recyclable materials, among others. Consequently, a review of the progress in TENGs based on green materials, which can be called green TENGs, becomes imperative to advance its sustainable development. To this end, this work comprehensively elucidates the development of green TENGs from the perspective of materials processing and treatment degree for the first time. Various green TENGs, including food waste, discarded daily‐use items, plant organs, biodegradable industrial products, and natural cellulose, are meticulously categorized. This review not only systematically synthesizes the latest research advancements in green TENGs, but also offers insight into their processing methodologies, working characteristics, and potential application scenarios. Finally, it envisions the challenges, proposed solutions, and future research directions for the development of green TENGs.
