Computer graphics representation of Buckminsterfullerene, C60 (green spheres), fitting nicely inside the channels of the zeolite VPI5 (Virginia Polytechnic Institute), a framework structured solid. VPI5 has large unidirectional pores that can admit large organic molecules. Zeolite structures present an ideal environment for shape-selective catalysis. A number of industrial processes use zeolite catalysts, notably in the cracking of petroleum. The isolation of the fullerenes, novel forms of carbon, by Huffmann et al in 1990, initiated much research into their chemistry & potential uses.
