Emerging organic pollutants (EOP) are present in many commercial products and have been detected in different aquatic environments in different parts of the world. Nanocomposite clays and / or land diataomácea / TiO2 have the potential to address problems related to pollution caused by EOP. However, some parameters must be controlled such as the lack of selectivity generated reactions, especially by photocatalysis, chemical affinity between support and active site and the generation of hydroxyl radicals efficiently. The development of catalysts based on this semiconductor, catalytic selectivity is potentially of great importance. Another relevant parameter for photocatalytic reactions is the required absorption band for excitation of the semiconductor, so the use of complexes such as metalloporphyrins can contribute to the absorption of radiation of the same in the visible region and increase efficiency in generation of radicals hydroxyl. Among the different existing supports, the functionalized natural clays or pillared with titanium dioxide can become excellent material for this purpose, by allying advantages of both as abundance, low cost, inertness and non-toxicity, the titanium as a strong power of photo oxidation and high stability against corrosion (photo and chemistry). Another very interesting alternative catalyst can be created with the use of biogenic silica, diatomaceous earth originating from diatom as silica source to be functionalized as various organic groups for subsequent bonding with active species. Additionally synthetic ironporphyrins recognized selective catalysts for oxidation reactions so as to degrade various pollutants classes, they may be incorporated in these matrices. Our research group has been dedicated to the development of multifunctional catalysts for economically viable processes and as close as possible to the principles of green chemistry, with not only academic application viability as industrial within this principle. The objective of this project is to synthesize and characterize multifunctional solid materials, based on titanium and ironporphyrins from natural clays (from Brazil or Spain), or arrays of silicates, from frustules diatomaceous earth, which are effective materials for multifuncioanais employed as catalysts in advanced oxidation reactions. Therefore, initially it is intended to functionalize clays and diatomaceous earth with commercial alkoxides employing the sol-gel method . Additionally, in order to increase the catalytic efficiency of titanium ions and promote the multifunctionality of the catalyst, second generation of ironporphyrins will be incorporated in these matrices. The innovative nature of this project will be the use of diatoms (or diatomaceous earth) as silicon source, after its functionalization with organic groups, by sol-gelmethod , via free silanols groups, they will also be used for the immobilization of second generation ironporphyrins functionalization or with titanium alkoxides and may be directly employed in the treatment of emerging organic pollutants, especially ibuprofen and acetyl salicylic acid, and oxidation of cyclohexane and ketone (Baeyer Villiger reaction).
