Abstract
Molecular sieve materials having a new framework structure; STA-28, are described. Silicoaluminophosphate (SAPO)-STA-28, Aluminophosphate (AlPO)-STA-28 and metal substituted STA-28 molecular sieves are further disclosed. The invention also relates to methods of preparation of STA-28 molecular sieve materials, catalysts and articles comprising the STA-28 molecular sieve materials, uses of the STA-28 molecular sieve materials as catalysts and in the treatment of exhaust gases. The use of 1,10-phenanthroline and derivatives thereof as a structure directing agent in the preparation of STA-28 are also described.
