Applications of molecular sieve materials have become of increasing interest in catalysis. The ability of these materials to differentiate on the basis of molecular size gives them a unique form of selective catalytic action with the additional benefit of high resistance to sorption of large poison molecules. Hitherto their major application has been realised with zeolites but new platinum catalysts possessing similar properties and based on a carbonaceous structure have now been developed in the Johnson Matthey Research Laboratories.
