1-Octene metathesis on silica supported Zr-doped NiMoO4 catalysts

This work presents results concerning the catalytic behaviour of silica-supported Zirconium (Zr)-doped NiMoO4 catalyst (NiMoZr1%Si) in the metathesis of 1-octene compared to that of the pure NiMoO4 (NiMo) and the un-doped supported catalyst (NiMoSi). The effect of doping on the physico-chemical properties of the catalysts is also investigated using X-ray diffraction (XRD), Fourier transformed infrared (FTIR), Raman spectroscopy, Brunnauer-Emmet-Teller (BET) method for determination of specific surface area, scanning electron microscopy (SEM), transmission electron microscopy coupled with energy dispersive X-ray spectrometry (TEM-EDX), and determination of acid-base properties by thermo-programmed desorption (TPD) of ammonia (NH3) and carbon dioxide (CO2), respectively.
