Abstract

In this project describes spectroscopic and electroanalytical properties of inorganofunctionalized spongolite (or micellar template silica) with zirconium (IV) and also of composite formed between the Zr (IV) and phosphoric acid following a new synthetic route . In a first step, it is intended to prepare and characterize by spectroscopic techniques (Nuclear Magnetic Resonance in solid state (NMR), Infrared Spectroscopy (FTIR), Thermogravimetric Analysis and Differential Thermal Analysis (TGA-DTA), Ultraviolet Visible Spectroscopy (UV-Visible), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX)), the inorganofunctionalized matrix with Zr (IV) and a composite formed between Zr (IV) and phosphoric acid. The voltammetric behavior of these supracited materials, after surface interaction with electron mediators, such as anionic (potassium hexacyanoferrate and / or sodium nitroprusside) and cationic (phenothiazines, ferrocene and others) species, will be tested. Therefore these studies aim the mounting of analytical systems for the determination of drugs and other species of biological interest, using cyclic voltammetry, differential pulse voltammetry, square wave voltammetry and chronoamperometry. Additionally it is intended to test the catalytic properties these materials in the selective conversion of glycerol into acrolein (an important intermediate for the production of acrylic acid).
