Engineering the Framework Cobalt and Hierarchical Pores of Aluminophosphates for Enhanced Performance in n‐Butene Skeletal Isomerization
Source abstract
Abstract
Abstract An effective method is proposed to synthesize a hierarchical Co‐doped AlPO4 molecular sieve (CoAIP‐CTAB). For the obtained zeolite, both framework and extra framework Co are firstly established and identified by X‐ray absorption fine structure (XAFS). The percentage of framework Co (P–O–Co–O–P) is estimated to be 82%. Due to the hierarchical structure and abundant Co sites in the framework, CoAIP‐CTAB nanocrystals have shown high catalytic activity and stability for the catalytic conversion of n‐butenes to isobutene at mild temperature (350 °C) without gas dilution. This novel synthesis strategy may inspire the design of similar types of industrial zeolite catalysts for selective reactions.
