“…Carbon-based three-dimensional (3D) architectures have attracted considerable attention in the past two decades due to their unique properties, such as huge surface area, interconnected porous structures, and macroscopic bulky shape, enabling them to be one of the most promising materials for water treatment [1][2][3][4][5][6]. However, the carbon-based 3D porous networks have limited compatibility and most of them only show affinity to certain category of contaminants [7][8][9][10][11].…”

The increasing demand of clean water and effective way to recycle industrial wastewater has offered a new application for carbon-based three-dimensional (3D) porous networks as sorbents due to their superior sorption abilities. Through the surface modification and hybridization with functional materials, the physical and chemical properties of the 3D carbon-based materials can be engineered. In this work, graphene-MoS 2 aerogels (GMAs) with bulky shape are synthesized via a one-pot hydrothermal method. The obtained GMAs show quick sorption rate and high sorption capacity towards a wide variety of contaminants. The sorption covers not only organic solvents or organic dyes, but also toxic heavy metals ions such as Hg 2+ and Pb 2+ . More importantly, the sorption capacity towards metal ions can be optimized by simply changing the loading amount of MoS 2 .

“…These materials have received increasing attention as an oil-absorbing material in oil/water separation for their microscale roughness in the integral fabric and their native porosity (Bi et al 2013;Wang et al 2013). Liu et al (2014) prepared superhydrophobic and superoleophilic SiO2-modified cotton for oil/water separation via a sol-gel process, which was initially pretreated by NaOH aqueous solution.…”

a This paper presents a facile and versatile strategy to fabricate robust and superhydrophobic/superoleophilic cotton for the removal of oils and organic solvents from polluted water. The superwettability cotton was prepared via in-situ hydrolysis of tetraethoxysilane (TEOS) on the cotton fiber surface using polyvinylpyrrolidone (PVP) as a coupling agent and subsequent hexadecyltrimethoxysilane modification. By simply adjusting the molecular weight of PVP and the concentration of NH3•H2O, the surface roughness of SiO2-modified cotton fibers could be well controlled to generate cotton fibers with excellent superhydrophobicity. The prepared cotton fibers were used as superabsorbents for oil/water separation. It absorbed up to 35 times and 50 times its own weight of nhexane and chloroform, respectively, while repelling water completely. After collecting the absorbed oils via a simple squeezing method, the cotton could be reused for at least 5 cycles. Moreover, the whole procedure was carried out in a mild environment, with no intricate instruments or toxic reagents.
