In this paper, we report a study of the influence of the synthesis method on the properties of mixed metal oxides. For this, the syntheses of the mixed oxide by chemical coprecipitation and modified polymeric precursor (MPP) methods containing Ni2+, Zn2+, Al2+, and Zr4+ were conducted. For this purpose, the samples were characterized by X-ray powder diffraction, which showed defined peaks for the mixed metal oxides (NiO, ZnO, and ZrO2). The interaction of H2 with mixed oxides has been investigated using temperature-programmed reduction (H2-TPR); this result showed that the modified polymer precursor method favored the presence of the peak at elevated temperatures. The N2 physisorption (BET method) showed that the polymer precursor method provided higher specific surface areas and basic site numbers in relation to the coprecipitation method. Thermogravimetric analysis of the systems decomposition revealed their disintegration at ~550 °C and resulted in mixed metal oxides in both methods.
