Recyclable Joule heated low shrinkage carbon nanofiber aerogels for microscale oil/water separation

Construction of a carbon nanosphere aerogel with magnetic response for efficient oil/water separation

“…However, the existing carbon aerogels used for oil adsorption have many problems, such as toxic or expensive raw materials, complex preparation process, low adsorption capacity and poor reusability, which greatly limit their application. 43,44 For example, Cheng et al 45 synthesized NiCo@rGO aerogel microspheres by electrospraying, metal crosslinking immobilizing and thermal reduction, and the adsorption capacity of the oil/organic solvent was 270 g −1 . Although it showed excellent adsorption performance, the preparation process was complex and the cost of graphene was high.…”
