Production Of Ni@Mo Core-shell Nanoparticles As The Catalyst And Investigation Of Effect Of Clay Thickness As The Support Of Nano Core-shell Catalyst On The Loading And Dispersion Of Ni@Mo Nanoparticles

Ni core-Mo shell nanoparticles (NPs) have been synthesized through a polyol reduction chemistry inethylene glycol (EG) with polyvinylpyrolidine (pvp) stabilizers by macrowave radition. A combination of transmissionelectron microscopy (TEM), UV-vis spectroscopy and scanning electron microscope (SEM) has been used tocharacterize the core-shell nanoparticle catalysts. The UV-vis spectra indicated the formation of core-shell structure inthe bimetallic Ni@Mo nanoparticles. Ni@Mo nanoparticles with an average particle size of 53 nm have been observedin SEM image. Ni@Mo nanoparticles have been supported on clay with different thickness via pervaporation method.The Ni@Mo/clay composite has been characterized by scanning electron microscope (SEM) and inductively coupledplasma emission spectroscopy (ICP). Among the catalysts studied, Ni@Mo/clay with the average thickness of 2mmpresents the highest loading Ni@Mo.
