“…Aerogels: Aerogels directly prepared from natural products were also applied for ideal oil sorption materials. By simple pretreatment of natural products which contains numerous celluloses, for example, corn stover [ 175 ], sugarcane bagasse [ 73 ], pomelo peel [ 74 ], and so forth, researchers fabricated various porous aerogels and composite aerogels with 3D porous structure. Cheng et al prepared cotton aerogels and cotton/cellulose composite aerogels and found that the composite aerogels exhibited better oil sorption performance and mechanical stability than that of pure cotton aerogels thanks to their own distinctive characteristics of cotton and cellulose [ 72 ].…”

Oil spill on sea surfaces, which mainly produced by the oil leakage accident happened on tankers, offshore platforms, drilling rigs and wells, has bring irreversible damage to marine environments and ecosystems. Among various spill oil handling methods, using sorbents to absorb and recover spill oils is a perspective method because they are cost-effective and enable a high recovery and without secondary pollution to the ecosystem. Currently, sorbents based on biomass materials have aroused extensively attention thanks to their features of inexpensive, abundant, biodegradable, and sustainable. Herein, we comprehensively review the state-of-the-art development of biomass-based sorbents for spill oil cleanup in the recent five years. After briefly introducing the background, the basic theory and material characteristics for the separation of oil from water and the adsorption of oils is also presented. Various modification methods for biomass materials are summarized in section three. Section four discusses the recent progress of biomass as oil sorbents for oil spill cleanup, in which the emphasis is placed on the oil sorption capacity and the separation efficiency. Finally, the challenge and future development directions is outlined.

“…Lei et al further enhanced the adsorption capacity of cornstalk-based hydrogel by crosslinking water-soluble polysaccharides and cornstalk cellulose [23]. Chen et al used NaOH and NaClO to successfully treat cornstalk and obtain cellulose fibers with polyvinyl alcohol (PVA) as a binder for preparing superhydrophobic and superoleophilic aerogels with excellent adsorption capacity [24]. In all cases, NaClO, NaClO 2 , or LiBr were exploited to obtain or dissolve cellulose.…”

Cellulose-based aerogel has attracted considerable attention for its excellent adsorption capacity, biodegradability, and renewability. However, it is considered eco-unfriendly due to defibrillation of agriculture waste and requires harmful/expensive chemical agents. In this study, cornstalk rind-based aerogel was obtained via the following steps: green H2O2/HAc delignification of cornstalk rind to obtain cellulose fibers, binding with carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) and freeze-drying treatment, and hydrophobic modification with stearic acid. The obtained aerogel showed high compressive strength (200 KPa), which is apparently higher (about 32 kPa) than NaClO-delignified cornstalk-based cellulose/PVA aerogel. Characterization of the obtained aerogel through SEM, water contact angle, etc., showed high porosity (95%), low density (0.0198 g/cm−3), and hydrophobicity (water contact angle, 159°), resulting in excellent n-hexane adsorption capacity (35 g/g), higher (about 29.5 g/g) than NaClO-delignified cornstalk-based cellulose/PVA aerogel. The adsorbed oil was recovered by the extrusion method, and the aerogel showed excellent recyclability in oil adsorption.
