Intercalation of Platinum Complex in LDH Compounds

Intercalation of platinum complex was carried out in [ZnAl], [MgAl], and [CuAl] LDH matrix by a new method including hydrothermal synthesis. Free carbonate products were obtained. XRD and FTIR studies show the total exchange. However, the geometry of the local environment of the platinum atom in the complex appeared to be modified during intercalation. By thermal treatments and reduction in ethylene glycol, metallic particles dispersed on oxide powder were obtained. The resulting calcined products could have some interest in heterogeneous catalysis.
