“…In general, an ideal adsorption material needs to have the following characteristics: high selectivity, low density, good recyclability, and an environmentally friendly composition. [ 219 ] The abundant reactive functional groups of BC aerogels mean that functional enrichment can be easily realized. Moreover, the 3D nanofiber structure of BC presents many advantages in adsorption applications.…”

Bacterial cellulose (BC) is an environmentally friendly biomaterial that is widely investigated because it possesses a unique hierarchical nanofiber network structure as well as extraordinary performance. In this review, the formation of the BC hierarchical nanofiber network structure from the perspective of biosynthesis is illustrated based on its basic chemical and crystal structure. Moreover, the design and processing of BC-based advanced materials through biosynthesis, physical, and/or chemical modification are also reviewed. The intrinsic characteristics of BC, derived from its hierarchical structure, are analyzed to understand its structure-property-application relationships. The applications of advanced BC-based materials are reviewed, such as high-strength structural materials utilizing the properties of nanofibers, energy conversion and storage, bioelectronic interfaces, environmental remediation, and thermal management applications utilizing the ion transport properties and 3D network structures of these materials. In addition, the authors also offer their opinions and potential future research directions for sustainably developing BC-based materials.

Cellulose-based aerogels have become promising adsorbents for organic pollutants and spilled oil due to their high selectivity and excellent sorption capacity. However, the high costs of preparation limit their practicality. In this study, cellulose fibers were fabricated from corn straw via simple alkaline pulping and bleaching. A cellulose aerogel (CA) was then prepared by the freeze-drying method with polyvinyl alcohol as the binder. After treatment with methyltrimethoxysilane by facile chemical vapor deposition, a modified cellulose aerogel (MCA) with water contact angles up to 154.8° was obtained, which exhibited superhydrophobicity. Importantly, the MCA has both high porosity (98.35–98.94%) and low density (16.33–23.95 mg·cm−3). In addition, the MCA can separate oil–water mixtures by gravity filtration with separation efficiency up to 97.3% and flux as high as 9827 L·m−2·h−1. This conversion of agricultural wastes into an efficient and high value-added adsorbing material is a promising development in the field of oil–water separation that offers a green and efficient strategy to combat the leakage of organic solvents and oil into the environment.
