Sorption is one of the most efficient methods to remediate the increasing oil spill incidents, but the currently available absorbents are inadequate to tackle such a global threat. Recently, numerous researchers have attempted to develop sustainable oil sorbents. Cellulose aerogels and foams, a type of lightweight porous material with excellent sorption performance, are one of the most promising candidates. Significant progress has been made in the past decade towards the development of cellulose porous materials as effective oil sorbents, with improvements in their oil sorption capacity, reusability, and enhanced multifunctionality, indicating their potential for oil spill remediation. This article reviews recent reports and provides a comprehensive overview of the preparation and modification strategies for cellulose porous materials, with a specific emphasis on their oil sorption performance and structure control. We also focus on the burgeoning 3D printing technology within this field, summarizing the latest advances with a discussion of the potential for using 3D printing to customize and optimize the structure of cellulose porous materials. Lastly, this review addresses current limitations and outlines future directions for development.
吸附是修复日益增多的石油泄漏事故最有效的方法之一，但目前可用的吸附剂不足以应对这种全球威胁。最近，众多研究人员试图开发可持续的石油吸附剂。纤维素气凝胶和泡沫是一种具有优异吸附性能的轻质多孔材料，是最有前途的候选材料之一。在过去十年中，将纤维素多孔材料开发为有效的石油吸附剂方面取得了重大进展，其吸油能力、可重复使用性和多功能性都有所提高，这表明它们在石油泄漏修复方面具有潜力。本文综述了近期的报告，并全面概述了纤维素多孔材料的制备和改性策略，特别强调了它们的吸油性能和结构控制。我们还关注该领域新兴的3D打印技术，总结最新进展，并讨论使用3D打印定制和优化纤维素多孔材料结构的潜力。最后，本综述阐述了当前的局限性并概述了未来的发展方向。
