Abstract

Multilayered porous hierarchical structure of graphene/ZnFe2O4 hybrids was prepared via in situ hydrothermal growth of ZnFe2O4 nanocrystals within interlayer space of reduced graphene oxide, which demonstrated a high specific area of 117 m2∙g−1 and rational porous structures. Batch adsorption studie...
