<p>A combinatorial method is provided for the preparation and screening of heterogeneous catalysts. The method comprises the steps of: (I) providing a library of elemental catalysts; (II) reacting the catalysts with a carbon source to form product directly on the catalyst; and (III) screening the products to evaluate the catalysts. In preferred embodiments the method is used for preparing and screening catalysts for making carbon fibrils. Catalysts are prepared using a multiple gun sputtering deposition system. The library of catalysts is supported on a substrate.</p> |
