DIRECT INCORPORATION OF IRON COMPLEXES INTO SAPO-34 (CHA) TYPE MATERIALS

摘要

Fe-SAPO-34 silicoaluminophosphates having Fe2+ organic complexes and methods for their direct synthesis in the absence of a co-templating agent are described. Fe-SAPO-34 silicoaluminophosphate having Fe3+ located in extra-framework locations within the pores of cages of the crystal are described. They are prepared by calcining the Fe-SAPO-34 silicoaluminphosphates containing Fe2+ polyamine complexes. Methods of using the Fe-SAPO- 34 having Fe3+ located in extra-framework locations within the pores of cages of the crystal in the treatment of exhaust gases are described.
