摘要：

Porous carbon/Fe3O4 nanocomposite (PC/Fe3O4 nanocomposite) was prepared from peanut shells as biowaste material and ferrous ferric oxide and studied by various analyses such as FT-IR, SEM, TEM, BET, VSM, TGA and atomic absorption spectrometry analysis. The use of porous carbon which obtained from peanut shells as biowaste material and pyrolysis with magnetic iron oxide causes synergy and increases the catalytic ability of magnetic iron oxide. PC/Fe3O4 nanocomposite was successfully applied as a recoverable magnetite heterogeneous catalyst for the condensation reaction of ethyl acetoacetate, hydrazine hydrate, malononitrile and aromatic aldehyde at 100 degrees C under solvent free condition to give pyranopyrazole derivatives in high yields and short reaction times.
