TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl radical)‐mediated oxidized cellulose nanofibers (TOCNFs), which are derived from abundantly available wood biomass, possess uniform and ultrafine diameters of 3–10 nm and high aspect ratios, and are functionalized with carboxyl groups. The fabrication process of TOCNFs is more environmentally friendly than that of other types of cellulose, such as microfibrillated cellulose (MFC) and cellulose nanocrystals (CNCs), and TOCNFs possess a more uniform and ultrafine diameter. In recent years, TOCNF‐based adsorbents, nanocomposites, and membranes have been studied extensively in various fields, such as environmental remediation, energy, and smart materials. This review summarizes the recent advances in the applications of TOCNFs in the abovementioned fields. In particular, the preparation, adsorption ability, and removal efficiency of TOCNF‐based absorbents, separation performance of various kinds of TOCNF‐based membranes, wide applications of TOCNFs in energy storage and conversion, and TOCNF‐based smart materials are discussed. The beneficial role of TOCNFs in the abovementioned applications is highlighted, including their low environmental impact, high aspect ratio, high strength, ability to be functionalized, and renewability. It is believed that this timely review will facilitate further research on the innovation and applications of TOCNFs in fields such as environmental remediation, energy, and smart materials.

TEMPO氧化纤维素纳米纤维：适用于环境和能源应用的可再生纳米材料

TEMPO（2,2,6,6-四甲基哌啶-1-氧自由基）介导的氧化纤维素纳米纤维（TOCNF），其来源于大量可利用的木材生物质，直径均匀且超细，直径为3-10 nm，高纵横比，并且被羧基官能化。与其他类型的纤维素（例如微纤化纤维素（MFC）和纤维素纳米晶体（CNC））相比，TOCNF的制造工艺对环境更加友好，并且TOCNF的直径更均匀，更细。近年来，基于TOCNF的吸附剂，纳米复合材料和膜已在各个领域进行了广泛的研究，例如环境修复，能源和智能材料。这篇综述总结了TOCNF在上述领域的应用的最新进展。特别是其制备，吸附能力，讨论了基于TOCNF的吸收剂的去除效率，各种基于TOCNF的膜的分离性能，TOCNF在能量存储和转化中的广泛应用以及基于TOCNF的智能材料。强调了TOCNF在上述应用中的有益作用，包括它们对环境的低影响，高长宽比，高强度，功能化能力和可更新性。据信，这种及时的审查将有助于进一步研究TOCNF在环境修复，能源和智能材料等领域的创新和应用。强调了TOCNF在上述应用中的有益作用，包括它们对环境的低影响，高长宽比，高强度，功能化能力和可更新性。据信，这种及时的审查将有助于进一步研究TOCNF在环境修复，能源和智能材料等领域的创新和应用。强调了TOCNF在上述应用中的有益作用，包括它们对环境的低影响，高长宽比，高强度，功能化能力和可更新性。据信，这种及时的审查将有助于进一步研究TOCNF在环境修复，能源和智能材料等领域的创新和应用。
