Recyclable Joule heated low shrinkage carbon nanofiber aerogels for microscale oil/water separation
文献摘要：
Aerogels have shown great potential as oil adsorbents but their application to the removal of microscale oil from water and their recycling remains problematic.The present work proposed a freeze-shaping method for fabricating carbon nanofiber aerogels(CNFAs)based on the direct use of one-dimensional(1D)carbon nanofibers(CNF)rather than carbonization of polymer aerogels.This technique greatly re-duces volume shrinkage and increases the three-dimensional(3D)structural stability of the material.Car-bon nanotubes(CNT)and gelatinized starch were incorporated in these aerogels as a conductive enhance-ment agent and binder,respectively,forming a"vine(CNT)-wrapped tree(CNF)"structure that improved mechanical and Joule-heating performance.The effects of glutaraldehyde added to aerogels as a cross-linking agent on mechanical properties and microstructure were also systematically investigated.The optimized CNFAs combined with low density,high porosity,good elasticity,and superior Joule-heating efficiency along with suitable adsorption capacity,excellent selectivity,and cycling stability.This mate-rial was able to selectively remove 87％and 92％of microscale acetone and dimethylformamide(DMF),respectively,from the water after nine cycles of adsorption and Joule-heating.The present work demon-strates a novel means of designing and fabricating a low shrinkage CNFA with outstanding Joule-heating performance having potential practical applications in the remediation of organic pollution.
