Acid–base properties of the products of thermal decomposition of [М(А)6]х[М1(L)6]у (where M is Co, Cr, Cu, Ni; M1 is Fe, Cr, Co; A is NH3, 1/2 en, 1/2 pn, CO(NH2)2; and L is CN, 1/2C2O4) binary complexes in air and their catalytic properties in the oxidation reaction of ethanol with atmospheric oxygen are studied. It is found that these thermolysis products are mixed oxides of the central atoms of complexes characterized by pH values of the zero charge point in the region of 4–9, OH-group sorption limits from 1 × 10–4 to 4.5 × 10−4 g-eq/g, OH-group surface concentrations of 10–50 nm–2 in 0.1 M NaCl solutions, and Ssp from 3 to 95 m2/g. Their catalytic activity is estimated from the apparent rate constant of the conversion of ethanol in CO2. The values of constants are (1–6.5) × 10–5 s–1, depending on the gas flow rate and the Ssp value.
