Abstract
We report the fabrication and characterization of a magnetically recyclable Fe3O4@Nico@Ag catalyst for reduction reactions in the liquid phase. Fe3O4 is a magnetic core and nicotinic acid was used as the linker for Ag. The characterization was done with X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, vibrating sample magnetometry (VSM), and ultraviolet-visible spectroscopy. VSM measurements proved the superparamagnetic property of the catalyst.
This article reported the synthesis of a magnetic recyclable Fe3O4@Nico@Ag nanocatalyst and its use for the hydrogenation of 4-nitrophenol and 4-nitroaniline. The catalyst can be used efficiently for the hydrogenation of nitroaromatics.
