Abstract
The composite on the basis of copper-supported alumina, used for the obtaining copper phthalocyanine from phthalonitrile as a precursor at temperatures close to r.t. (0–50°C), was prepared from a mixture of a copper salt with alumina and characterized by atomic force microscopy (AFM), X-ray diffraction, measurement of surface area and adsorption-desorption isotherms. It is shown that the height average of cubic-shape copper particles deposited over an alumina surface is 142 ± 30 Å. The synthesis method for the alumina-supported copper affects drastically the available area of alumina that diminishes the surface catalytic properties. However, the supported copper particles act as a driving force for obtaining metal phthalocyanines at relatively low temperature.
