Al-rich mesoporous FSM-16 materials: Synthesis, characterization and catalytic properties

Al-rich mesoporous FSM-16 materials (Si/Al=5–16) have been synthesized using CTMABr as a surfactant. Additional mechanistic insight into the formation of Al-FSM-16 materials is gained from careful characterization of the samples collected at various stages of the preparation procedure by means of XRD and MAS NMR ( 29 Si and 27 Al). These results suggest that the single sheet structure of kanemite breaks up during the intercalation process and regains its structure upon the addition of Na-aluminate and then condensation occurs between the adjacent silicate layers, leading to the formation of mesoporous Al-FSM-16 materials. Fe-exchanged Al-FSM-16 samples were also prepared and their performance tested in the decomposition of N 2 O in a fixed bed reactor.
