Synthesis And Characterization Of Nickel-Molybdenum Catalysts Supported On Copper Orthophosphates

Abstract

Abstract Synthesis of a pure copper orthophosphate (CuP) prepared by Coprecipitation, and CuP modified by impregnation of NiMo (2-14 wt % of Ni-Mo oxide) have been carried out. The solids obtained were investigated as synthesized or after calcination by various physico-chemical techniques such as X-Ray Diffraction (XRD), Infrared Spectroscopy (IR), Thermogravimetric analysis (TGA), and differential thermal analysis (DTA). The results revealed that the solids NiMo/CuP consisted of copper orthophosphate Cu3(PO4)2 as major phases, together with NiMoO4 as minor phase. The diffraction lines of NiMoO4 increase by increasing the nickel-molybdenum content.
