Abstract

This Scientific Initiation Project is involved in a Research Grant funded by FAPESP (Process: 2015/24136-4). Hybrid films containing a polyoxometalate, silicotungstic acid, (HSiW) will be prepared and characterized by incorporation of this one in an organically modified silicate network, "ormosil" and also by layer-by-layer self-assembly electrostatic adsorption of HSiW with cationic species. The electrocatalytical properties of the films will be investigated toward two pesticides: ametryn and hexazinone. The materials produced here can contribute to develop systems able to detect these mentioned species. (AU)
