This work is devoted to the investigation of local raw materials, its preparations processes and characterization technique of a Cu-Fe-O applied as a catalyst for hydrocarbon (HC) oxidation. Samples obtained by high temperature solid state method using copper oxide (CuO) and iron oxide (Fe2O3) and by wet chemical synthesis method using water as a solvent, applying iron nitrate (Fe(NO3).9H2O) and copper nitrate (Cu(NO3)2.3H2O). In wet synthesis method the thermal treatment at 100oC and 150oC, water and nitrates removed from the sample, respectively. Three samples prepared at different quantitative precursor composition that is Fe/Cu = 0.5, 1 and 2 for each principal procedures. Mixing and calcinations at 850oC for 8hours were the common unit operations for both preparation routes. In this work it is demonstrated that, the nature of preparation ways, the structural property of precursors and the quantitative precursor composition affects the formation of desired phase, crystal property, size and strain of crystals, microstructure and specific surface area of the sample; which are among the most relevant physical and chemical properties for the catalytic activity. The phase identification, structural property and morphology analysis of samples were characterized by X-ray diffraction and Blaine air permeability apparatus and the samples prepared by solid state method on a precursor composition of Fe/Cu = 0.5 showed optimized property.
