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 Cu 3 (PO 4 ) 2 as major phases, together with NiMoO 4 as minor phase. The diffraction lines of NiMoO 4 increase by increasing the nickel-molybdenum content.
