Ultralight and Superelastic Nanofiber Aerogels with In-Situ Loaded Polypyrrole for High-Efficient Cr(VI) Adsorption

Constructing 3-D nanomaterial-based adsorbents with good mechanical properties has attracted increasing attention. This paper reports a simple strategy to prepare ultralight and superelastic aerogels as efficient for heavy metal Cr(VI) in wastewater by in-situ loading of polypyrrole on cellulose acetate nanofibers followed freeze-drying method. The obtained aerogel possesses obvious porous cross-linked structure, which is uniformly coated the nanofiber surface. Besides, shows high compressive strength 14.49 kPa, can be processed into any desired shape. Especially, due presence large specific surface area porosity, significant adsorption maximum capacity 244.65 mg/g. present work proposes high-quality efficiently adsorbing Cr(VI).
