Fullerenes Research

SRI is pursuing a vigorous research program on the production and properties of fullerenes and their derivatives. We have assembled a facility for producing and separating substantial quantities of fullerene materials. The derivatives being studied include those formed by attaching other groups on the fullerenes (functionalized fullerenes), by substituting some of the carbon atoms by other elements (dopyballs), and by encasing atoms of various metals within the fullerene cage (endohedrals).

SRI has pioneered research on new fullerene materials like carbon nanotubes and polyhedral particles as well as encaging of other metal crystals inside the polyhedral nanoparticles. The program is uncovering opportunities for new applications, for example in the area of materials, catalysis, and pharmaceuticals. Research at SRI has identified fullerenes as efficient hydrogen-transfer catalysts.

Recent contracts are summarized below:

• A multiyear contract with MITI, Japan,to develop a basic understanding of production processes and properties of fullerene materials. This contract led to several proprietary techniques for purifying fullerenes as well as led to the discovery of nanoparticles and nanotubes filled with other metals.
• A three-year contract with the U.S. Department of Energy explored the use of fullerene-derived materials for methane activation.
• A two-year commercial contract studied the factors controlling formation of fullerenes from hydrocarbons under pyrolysis conditions.
• Several SBIR Phase I and II subcontracts covered fullerene production and specific applications such as catalysts for upgrading resids, ion propulsion, and permselective membranes.
• A project funded through SRI's investment program explored commercial applications of fullerene-derived materials in diverse areas such as energy conversion and storage, optical materials, catalysis, and pharmaceuticals.
