“…More recently, research interests have been drawn to converting natural biomass materials and even waste carbonaceous materials into hydrophobic carbon aerogel absorbents. [118][119][120][121][122][123][124][125] For example, our group has demonstrated the preparation of twisted carbon fi ber (TCF) aerogels through the direct pyrolysis of raw cotton. [ 124 ] The fi brous structure of cotton could be maintained after the pyrolysis, but the resulting carbon fi bers became more twisted ( Figure 7 a-c).…”

“…Similarly, our group has also successfully converted waste materials, i.e., waste paper, into carbon microbelt (CMB) aerogels, which could also selectively absorb oil from the oil/water mixture. [ 125 ] As the raw materials are sustainable and cost-effective, both TCF aerogels and CMB aerogels are believed to be highly promising for large-scale production and practical applications. Besides the natural abundant carbonaceous precursors, various other synthetic 3D architectures were also carbonized through pyrolysis to achieve carbon-based 3D absorbents, such as cellulose aerogels, polymeric aerogels, commercial polymer sponges, etc.…”

The increasing number of oil spill accidents have a catastrophic impact on our aquatic environment. Recently, special wettable materials used for the oil/water separation have received significant research attention. Due to their opposing affinities towards water and oil, i.e., hydrophobic and oleophilic, or hydrophilic and oleophobic, such materials can be used to remove only one phase from the oil/water mixture, and simultaneously repel the other phase, thus achieving selective oil/water separation. Moreover, the synergistic effect between the surface chemistry and surface architecture can further promote the superwetting behavior, resulting in the improved separation efficiency. Here, recently developed materials with special wettability for selective oil/water separation are summarized and discussed. These materials can be categorized based on their oil/water separating mechanisms, i.e., filtration and absorption. In each section, representative studies will be highlighted, with emphasis on the materials wetting properties and innovative aspects. Finally, challenges and future research directions in this emerging and promising research field will be briefly described.

“…[19] Unfortunately,c ommerciala pplications of CNT-a nd graphene-based absorbent materials are still severely limited, because of the complex equipment and high cost involved in their preparation. Other candidates including carbona erogels derived from raw cotton, [20] waste paper, [21] and bacterial cellulose, [22] although they have the merit of simpler fabrication procedure andl ower cost, do not show the desirable hydrophobicity.…”

A Superhydrophobic Sponge with Hierarchical Structure as an Efficient and Recyclable Oil Absorbent

et al. 2015

Oil/water separation is a worldwide challenge due to frequent oil spillages, and high‐performance absorbents are in high demand. In this work, a superhydrophobic sponge was fabricated by the polymerization of aniline, with subsequent simple immersion in n‐dodecylthiol. The polyaniline (PANI) constructed a nanoscale rough surface on the three‐dimension (3D) network of melamine sponge while n‐dodecylthiol reduced surface energy, thus lead to the superhydrophobicity. This superhydrophobic sponge could absorb a broad spectrum of oil and organics efficiently, with the highest 122 times of its own weight absorption capacity. Owing to the strong mechanical elasticity inherited from the pristine melamine sponge and stable adhesion of PANI, this sponge exhibited good recyclability through squeezing. More importantly, the fabrication procedure is facile, low‐cost and easily scalable. Thus, this superhydrophobic sponge is highly promising for absorption oil from water.

Porous carbon has received great attentions for electrochemical energy storage devices. In this study, we proposed a novel and scalable method to fabricate porous carbon, which contained macro and mesopores, from sustainable biomass raw material of cotton cellulose.MgO template, which acted as pore creator, was incorporated into the cellulose-derived carbon by absorbing a Mg(NO 3 ) 2 solution in cellulose fibers with subsequent drying and carbonization processes. After removing the MgO template by acid leaching, porous carbon was produced with a specific surface area as high as 1260 m 2 g -1 . The sample showed attractive electrochemical performances as the anode material for Li ion batteries (LIBs). The carbon anode delivered a high reversible capacity of 793 mAh g -1 at a current density of 0.5 A g -1 after 500 cycles. The carbon anode also showed a high-rate capability, and a capacity of 355 mAh g -1can be obtained at a current density of 4 A g -1 . A wide comparison with literatures also showed that the cotton-derived porous carbon was among the most promising carbon-based anodes forLIBs.
