Selective catalytic reduction of NO with NH on mixed alumina–iron (III) oxide pillared montmorillonite “Cheto” Arizona, modified with hexamminecobalt (III) chloride
Montmorillonite intercalated with mixed alumina–iron (III) oxide pillars and promoted with hexamminecobalt (III) chloride was studied in selective catalytic reduction of NO with NH 3 . Pillaring process extended the interlayer spacing by 0.236 nm and increased specific surface area (SSA BET ) from 3...

| description | Montmorillonite intercalated with mixed alumina–iron (III) oxide pillars and promoted with hexamminecobalt (III) chloride was studied in selective catalytic reduction of NO with NH 3 . Pillaring process extended the interlayer spacing by 0.236 nm and increased specific surface area (SSA BET ) from 33 m 2 up to 299 m 2 . Interlayer space width did not change after calcination process, but high temperature could cause decomposition of hexamminecobalt (III) – [Co(NH 3 ) 6 ] 3+ , possibly to Co 2+ . Promotion of hexamminecobalt (III) chloride to pillared clay did not significantly change SSA BET . The intercalation process influenced positively selective catalytic reduction activity, but very high formation of N 2 O was observed. Pillared clay, promoted with [Co(NH 3 ) 6 ] 3+ , showed higher selective catalytic reduction activity and much lower N 2 O formation than unpromoted, pillared sample. Clay with interlayer cations exchanged for [Co(NH 3 ) 6 ] 3+ , without pillaring, showed no selective catalytic reduction activity, but still produced high amounts of N 2 O. |
