抜粋

A complex copper aluminum double hydroxide phase with sulfate anions (sulfate phase), Cu0.67Al0.33(OH)2(SO4)0.15(CO3) 0.015·0.5H2O, was prepared by adding a mixed solution of aluminum sulfate and sodium hydroxide to a copper (II) ammine complex solution. Although the X-ray powder diffraction pattern of the sulfate phase was different from those of hydrotalcite-like compounds, the SEM, IR, thermoanalytical data, and anion exchange behavior suggested that the structure was lamellar. The basal spacing depended on the interlayer anion and increased in the following sequence: CO2-3 s ̌Cl-<Br-<SO2-4<NO-3 <CH3OO-. Thermal decomposition processes were also investigated.
