A new peroxo-method for Mg-Zr mixed oxide preparation has been applied. It has been established that this precursor after being heated up to 700 ºC is in the form of poorly crystalline Mg-Zr oxide. Thermal and X-ray diffractional analyses have shown that the oxide phase is formed directly from amorphous peroxocomplex, avoiding formation of intermediate Mg(OH) 2 phase. The peroxocomplex-mediated route allows achieving high degree of molecular homogeneity in the mixed oxide and high distribution of the active sites due to its low crystallinity. The prepared material is a potential catalyst for aldol condensation reaction.
