“…Recently, the use of renewable biomass resources, such as starch, alginate, chitosan, and cellulose as raw materials in the preparation of carbon aerogels has attracted great interest [203,204,205]. Porous cellulose aerogels prepared using cellulose may be a candidate for making carbon aerogels.…”

“…The specific surface area of carbon aerogels obtained by the direct pyrolysis of bamboo fibers is only 26.2 m 2 /g, and their maximum adsorption capacity for oil and organic solvents is only 51 g/g [204]. Therefore, the unique high 3D porosity and large specific surface area of the cellulose aerogel structure are key considerations in the quest to obtain carbon aerogels with good performance.…”

Due to its excellent performance, aerogel is considered to be an especially promising new material. Cellulose is a renewable and biodegradable natural polymer. Aerogel prepared using cellulose has the renewability, biocompatibility, and biodegradability of cellulose, while also having other advantages, such as low density, high porosity, and a large specific surface area. Thus, it can be applied for many purposes in the areas of adsorption and oil/water separation, thermal insulation, and biomedical applications, as well as many other fields. There are three types of cellulose aerogels: natural cellulose aerogels (nanocellulose aerogels and bacterial cellulose aerogels), regenerated cellulose aerogels, and aerogels made from cellulose derivatives. In this paper, more than 200 articles were reviewed to summarize the properties of these three types of cellulose aerogels, as well as the technologies used in their preparation, such as the sol-gel process and gel drying. In addition, the applications of different types of cellulose aerogels were also introduced.

Application of Sorbents for Oil Spill Cleanup Focusing on Natural-Based Modified Materials: A Review

Conventional synthetic sorbents for oil spill removal are the most widely applied materials, although they are not the optimal choices from an economic and environmental point of view. The use of inexpensive, abundant, non-toxic, biodegradable, and reusable lignocellulosic materials might be an alternative to conventional sorbents, with obvious positive impact on sustainability and circular economy. The objective of this paper was to review reports on the use of natural-based adsorbing materials for the restoration of water bodies threatened by oil spills. The use of raw and modified natural sorbents as a restoration tool, their sorption capacity, along with the individual results in conditions that have been implemented, were examined in detail. Modification methods for improving the hydrophobicity of natural sorbents were also extensively highlighted. Furthermore, an attempt was made to assess the advantages and limitations of each natural sorbent since one material is unlikely to encompass all potential oil spill scenarios. Finally, an evaluation was conducted in order to outline an integrated approach based on the terms of material–environment–economy.

“…Carbon aerogels (CAs) are special organic materials with high mesoporous volume, low density, continuous porosities and high specific surface area, owing to their unique 3D nano-network structures. [27][28][29][30] These physical characteristics give electrochemical, thermal and catalytic properties with wide applications in environmental fields. Wu et al found that CA particle electrodes were efficient for discoloration of RBRX dye(C 19 H 10 O 7 N 6 C l2 S 2 Na 2 ).…”

BACKGROUND Research on electrode materials with high electrochemical activity is of great importance for the electrochemical oxidation technique. In this work, an electrode comprising titanium dioxide nanotubes with tin oxide antimony (TiO2‐NTs/SnO2—Sb) with carbon aerogels (TSS‐CAs) was fabricated and used to degrade three isomers of dihydroxybenzenes. RESULTS It was observed that the TSS‐0.5%CAs electrode prepared with 0.5 wt% CAs possessed prominent pore structure and a larger specific surface area of 180.83 m2 g−1. Electrochemical measurements revealed that the TSS‐0.5%CAs electrode had enhanced electrochemical activity, larger electroactive area, and higher oxygen evolution potential. Relevant operational parameters including initial contaminant concentration, pH, electrolyte concentration and current density had significant effects on the electrocatalytic performance of the TSS‐CAs electrode. CONCLUSION It was demonstrated that a proper content of carbon aerogel could improve the structure and electrochemical performance of the TSS‐CAs electrode. The removal of catechol was higher than that of hydroquinone and resorcinol during electrochemical oxidation, due to its lower Gibbs free energy barriers. Oxidation of intermediates of dihydroxybenzenes by the TSS‐CAs electrode also was confirmed. © 2019 Society of Chemical Industry
