Synthesis and characterization of modified Nano composite from carbon multi wall nanotubes / zeolite by Palladium nanoparticles

Nanoparticles have been of special interest for many decades due to their diverse applications in a variety of fields such as biology, electronics and catalyst for organic reactions. In the application works nanoparticles have some limit to use because of agglomeration.to overcome this problem nanoparticles disperse in other support.In this work, first ZSM - ۵ type zeolite was modified by amino - propyltriethoxysilane (APTES). In the second step it was purchased Multi - walled carbon nanotubes ( MWNTs ) with carboxylic acid functional groups ( MWCNTs - ( COOH ) n ). Finally , ZSM - ۵ @ MWCNT composite with structure was obtained. Finally, Palladium Nano particles introduce to the ZSM - ۵ @ MWCNT and was characterized by various techniques such as Fourier transform infrared spectroscopy ( FT - IR ) ,X - ray diffraction ( XRD ) , thermo gravimetric analysis , differential thermal analysis ( TGA / DTA ) , scanning electron microscopy ( SEM ) , Brunauer - Emmett - Teller ( BET ) and used as catalyst for selective reduction of nitro aromatic compounds.
