Bioinspired Assembly of Carbon Nanotube into Graphene Aerogel with “Cabbagelike” Hierarchical Porous Structure for Highly Efficient Organic Pollutants Cleanup

Abstract: Nowadays, physical absorption has become a feasible method offering an efficient and green route to remove organic pollutants from the industrial wastewater. Inspired by polydopamine (PDA) chemistry, one-dimensional PDA-functionalized multiwalled carbon nanotubes (MWCNT-PDA) were creatively introduced into graphene aerogel framework to synthesize a robust graphene/MWCNT-PDA composite aerogel (GCPCA). The whole forming process needed no additional reducing agents, significantly reducing the contamination emissi… Show more

“…Carbon aerogels are frequently used as the selective adsorbent for oil/water separation due to the intrinsic characteristics , , . Oxygen and hydrogen containing groups in aerogels are decomposed in the hydrothermal or carbonization process, leaving the graphitization structure, which is mainly composed by low‐surface‐energy sp 2 carbon.…”

“…Moreover, CNTs were added to the graphene aerogel to improve the mechanical strength and specific surface area. The composite aerogels are more suitable for environmental clean‐up, especially for oil/water separation , , , . Zhan et al creatively introduced PDA‐functionalized carbon nanotubes into graphene aerogel to form a robust PDA/MWCNT/graphene composite aerogel with a novel “cabbagelike” hierarchical porous structure ( Figure ) .…”

“…Sol-gel technique has been commonly used to achieve it, in which gel would be formed in situ after injecting a sol solution (Amiri, 2016). CNTs have been proved to be an effective absorbent material, particularly to organic molecules, owing to their highly hydrophobic surface, unique internal tube cavity, and interstitial spaces between tubes (Hou, Du, Meng, Zhao, & Du, 2018;Zhan, et al, 2018). In addition, CNTs could provide a high flux for solute transport due to the atomic-scale smoothness of their walls and the molecular ordering phenomena inside the nanopores (Konduri, Tong, Chempath, & Nair, 2008).…”
