A novel method for the preparation of new synthetic, potentially catalytic clays has been discovered. In this method, a diverse variety of organic and-organometallic molecules can be directly incorporated during crystallization of the clay. This method has great potential for the incorporation of catalytically active species to create new heterogeneous catalysts. The catalyst precursors are organic-inorganic composites comprised of a layered silicate intercalated with such molecules as porphyrins or metalloporphyrins, organic aromatic dyes, a Cu(II) phthalocyanine dye, or bulky transition metal chelates. This procedure is readily applicable for introducing specific molecules for highly tailored applications, because successful templates include a variety of catalytically, electrochemically, and photochemically active species. Characterization studies were performed to establish the composition of the synthetic products, including x-ray absorption spectroscopy at NSLS. |
