CoFe 2 O 4 /C nano-sheets (NSs) have been synthesized by a facile molten salt method using cheap potassium fulvate as carbon source and sodium chloride as template. The morphology, crystallinity and composition of the materials were analyzed by TEM, XRD and XPS. The study on the catalytic performance of 4-nitrophenol (4-NP) shows that CoFe 2 O 4 /C-600 nano-catalyst has the highest catalytic activity and the corresponding apparent constant is 1.91 min -1 , this result is higher than that reported in most literatures. Catalytic kinetics of 4-NP reduction was studied in this article, and activation energy (E a ) was calculated to be 14.31 kJ mol -1 . The catalyst also shows good cycle performance and stability. This convenient method provides a reference for the synthesis of MFe 2 O 4 /C and other nano-metal oxides/C nanocomposite catalysts., (Copyright © 2019 Elsevier Ltd. All rights reserved.)
