Synthesis of the catalysts based on oxides of some d-elements

In this work, nanocomposite materials were synthesized on the basis of a mixture of nitrates of Ni (II), Zr (IV), Mg (II) and Al(OH)3 with glycine by the solution combustion method. The synthesized nanocatalysts with the composition xNiO/yZrO2/zAl2O3 (TiO2, MgO) are characterized by a high specific volume (0.80 ± 0.05 cm3/g), an average size (1.85 ± 0.05 nm) of pores, a relative specific surface area (180 ±8 m2/g) and a big monolayer capacity (3.17 ± 0.24 mol/kg). A hysteresis loop is observed in isotherms during the absorption of benzene vapours, while in the case of hexane it is absent. The resulting nanocatalysts can be used as a selective catalyst for the conversion of methane in a flow reactor.
