An important aspect of a catalyst is their surface area; the larger the surface area the more available sites there are for chemical interactions. For this reason, catalyst with a relatively high surface area are preferred. To achieve high surface area, one can reduce the size as seen in nanoparticles, or alternatively create a highly porous substance as seen in zeolites. By controlling the different synthetic routes, we are able to direct aspects such as surface features and roughness. We are able to combine these two, in tailor-made sol-gel materials. We are able to control the hydrophobicity; making them ideal candidates for recoverable catalyst. In this presentation, we will describe a synthetic protocol in which amine functionalized siloxy gels are synthesized in a one step process. The silane is prepared via the reaction with nitrate salts saturated with a bis(trimethoxysilylpropyl) and N-halosuccinimide (NXS) forming a porous gel. The bis(trimethoxysilylpropyl)amine is hydrolyzed in a presence of polar protic solvents and the halosuccinamides were added to the reaction mixtures as catalyst. Generated materials exhibited a porous framework with metal complexed within. These materials were able to maintain their amino moieties for further chemical applications. Structural and spectroscopic analysis of these samples was carried out by: 29Si NMR, 13C NMR, 1H NMR, TEM, SEM/EDX, TGA, FT-IR, and Raman techniques.
