Аннотация

Mixed copper-containing spinel-type compounds CuCr1Fe1O4, CuCr1Al1O4 and CuFe1Al1O4 were studied by means of XRD and HREM after calcination at 650 °C in the air and treatments in a hydrogen-containing medium at 270–210 °C (H2:He = 5:95; H2:CO:H2O = 50:7:43). The effect of the chemical nature of Mе3+ cation on the structural-morphological characteristics of oxide systems and their transformations in a reducing medium was investigated. It was shown that the nature of Me3+ cation makes it possible to control the structural characteristics, particularly in the reduced state.
