Green synthesis of amino-functionalized carbon nanotube-graphene hybrid aerogels for high performance heavy metal ions removal

In this study, the ultra-lightweight and robust three-dimensional graphene/polydopamine modified multiwalled carbon nanotube (MWCNT-PDA) hybrid aerogels were prepared via a viable green route and applied to highly efficient heavy metal ions adsorption. No additional reducing agents were required during the molding of the hybrid aerogel, thus greatly reducing the environment pollution emissions. The MWCNT-PDA in right amounts provided the hybrid...
