Computer graphics representation of the structure of the zeolite VPI5 (Virginia Polytechnic Institute),a framework structured solid. VPI5 has large unidirectional pores that can admit large organic molecules. The framework of this substance is constructed from sub-units of aluminium phosphate. Atoms of phosphorus & aluminium are coloured yellow,with oxygen in blue. The channels & interconnecting cavities formed by the structures of zeolites present an ideal environment for shape-selective catalysis. A number of industrial processes use zeolite catalysts,notably in the cracking of petroleum | |
