Polímeros de coordenação heterobimetálicos: Estudo experimental e atividade catalítica

Abstract

Proper polymeric catalysts in catalytic processes enable a considerable increase in the speed and yield of chemical reactions. In this field, in the last years, coordination polymers have been studied attempting such applicability. The catalysts synthesis of this kind is proving itself as a challenge, encouraging the research in the academic and industrial field. The present work aims to discuss about the coordination polymers synthesis and their characterization. The first phase of the research presents the synthesis of ten coordination polymers obtained as a consequence of concentration changes in 10, 30 and 50 per cent in mmol of the following transition metals: copper, cobalt, nickel and manganese. Then, the second phase reports the synthesized compounds characterizations using X-ray diffraction, absorption spectroscopy, thermogravimetry and catalysts trials. The results obtained indicated that between the synthesized polymers, the Cu-IDA compound was the one that presented better perfomance compared to manganese doped compounds. The comparative evaluation showed that copper-doped compounds have more satisfactory reaction in the reactions test, providing a greater product yield.
