The influence of the concentration of Mn<sup>2+</sup> in a solution for the hydrolysis of nanosized aluminum powder on the phase composition of the precursor and the content of manganese in samples of aluminum hydroxide is studied. Stages of the formation of catalysts from the precursors are studied by means of synchronic thermogravimetric (TG)-differential scanning calorimetry (DSC) analysis and X-ray phase analysis (XPA). The influence of the number of manganese ions in aluminum hydroxide on the phase composition and catalytic properties of MnO<inf>x</inf>-Al<inf>2</inf>O<inf>3</inf> systems in the reaction of the deep oxidation of methane is also studied. It is shown that an increase in the concentration of manganese ions in the solution for hydrolysis raises the content of unreacted aluminum and X-ray amorphous hydroxides in the precursors of the catalysts. It is established that the phase composition of the catalyst and the catalytic activity in the reaction of the deep oxidation of methane depend on the content of manganese in the precursor.
