Cellulose is the richest renewable polymer source on the earth. TEMPO-mediated oxidized cellulose nanofibers are deduced from enormously available wood biomass and functionalized with carboxyl groups. The preparation procedure of TOCNFs is more environmentally friendly compared to other cellulose, for example, MFC and CNCs. Due to the presence of functional carboxyl groups, TOCNF-based materials have been studied widely in different fields, including biomedicine, wastewater treatment, bioelectronics and others. In this review, the TEMPO oxidation mechanism, the properties and applications of TOCNFs are elaborated. Most importantly, the recent advanced applications and the beneficial role of TOCNFs in the various abovementioned fields are discussed. Furthermore, the performances and research progress on the fabrication of TOCNFs are summarized. It is expected that this timely review will help further research on the invention of novel material from TOCNFs and its applications in different advanced fields, including biomedicine, bioelectronics, wastewater treatment, and the energy sector.
纤维素是地球上最丰富的可再生聚合物资源。TEMPO 介导的氧化纤维素纳米纤维来源于丰富的木材生物质，并通过羧基官能化。与其他纤维素（例如 MFC 和 CNCs）相比，TOCNFs 的制备过程更加环保。由于存在功能性羧基基团，基于 TOCNF 的材料已在包括生物医学、废水处理、生物电子学等不同领域得到广泛研究。在这篇综述中，详细阐述了 TEMPO 氧化机制、TOCNF 的性质和应用。最重要的是，讨论了 TOCNF 在上述各个领域中的最新应用和有益作用。此外，还总结了 TOCNF 的制造性能和研究进展。预计这篇及时的综述将有助于进一步研究从 TOCNF 发明新型材料及其在生物医学、生物电子学、废水处理和能源领域等不同先进领域的应用。
