Resumo: |
The development of new materials with performance and optimized properties constitutes an area in constant expansion in sciences of the materials. In this work they had been prepared material based in the colloidal interaction of cobalt [CoOOH] with watery suspensions of clays of the montmorilonita type with intention to use to advantage and to combine the characteristics of ionic exchange and intercalation of an argilomineral with the ones of tack and conduction of a inorganic gel in an only material. The resultant mixing materials are interesting and promising; therefore they present synergistic behavior between the phases that constitute them. The mixing materials had been characterized by diffraction of X-ray (DRX), spectroscopy electronic (UV-Vile) and vibrational (FTIR) and analyze thermogravimmetric (TGA/DTA). Study of the electrochemical behavior in function of the water electrolyte solution it has supported was carried through using the technique of cyclical voltammetric (VC) and the results had been analyzed with sight its application as sensor of species redox and not redox. |
