Full TextAbstract
In this work, a novel structured silica-supported Preyssler nano particles /carbon nanotube composite is synthesized. Multiwalled carbon nanotubes (MWCNTs) were synthesized by catalytic chemical vapor deposition method (CVD). The characterization of the materials by the Fourier transform infrared spectroscopy (FTIR), and Transmition electron microscopy (TEM), showed that the functionalization of MWCNTs by silicasupported Preyssler nano particles was successfully achieved via impregnation method. It has been found that the synthesized composite with 30 wt% loading is highly active catalyst in synthesis of β-acetamido ketones/esters and shows high yields in this reaction. This catalyst can be easily recovered and reused for many times without a significant loss in its activity.
